**Answer:**

**a= 180-60-55=65 **

**we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a. **

**b=180-90-65=25**

**the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b. **

**c=25 **

**c is 25, because two angles on both sides of a X is the same **

Equilateral triangles are

acute triangles.

Scalene triangles are

acute triangles.

Right triangles are

acute triangles.

Obtuse triangles are

isosceles triangles.

**Answer:**

Equilateral triangles are always acute triangles.

Scalene triangles are sometimes acute triangles.

Right triangles are never acute triangles.

Obtuse triangles are sometimes isosceles triangles.

**Step-by-step explanation:**

Equilateral triangles are always acute because each angle is 60⁰.

Scalene triangles have sides that are different lengths. They can be right, obtuse, or acute.

A right triangle is never acute because it has a 90⁰ angle. Acute means all angles are less than 90⁰.

An obtuse triangle can be either scalene or isosceles. It always has one angle greater than 90⁰ (obtuse).

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

Complete the equation so it will have no solution. 5x - 8 = _ +2

**Answer:**

5x

**Step-by-step explanation:**

If the blank were to be occupied with 5x there would be no solutions

Observe...

5x - 8 = 5x + 2

* subtract 5x from each side *

5x - 5x cancels out

5x - 5x cancels out

we're left with -8 = 2

which is not true

Hence if the blank = 5x the equation will have no solution

Find the perimeter of the right triangle. If necessary, round to the nearest tenth. a. 13 in. b. 169 in. c. 60 in. d. 30 in.

Question: Find the perimeter of the right triangle. If necessary, round to the nearest tenth. 4 cm 15 cm a. 15.5 cm

b. 30 cm

c. 60 cm

d. 34.5 cm

**Answer:**

**d. 34.5 cm**

**Step-by-step explanation:**

Applying

Perimeter of the right triangle (P) = a+b+c

P = a+b+c.................... Equation 1

But we can find the hyotenuse (a) using pythagoras theorem

a² = b²+c²

a = √(b²+c²)............... Equation 2

Substituting equation 2 into equation 1

P = √(b²+c²)+b+c................... Equation 3

From the diagram,

Given: b = 4 cm, c = 15 cm

Substitute these values into equation 2

P = √(4²+15²)+4+15

P = √(241)+4+15

P = 15.5+4+15

P = 34.5 cm

Hence the right answer is d. 34.5 cm

3(3u-2)=2(3u+3)

What is the steps

Hopes this helps:

Answer: u = 4

1. Expand.

9u - 6 = 6u + 6

2. Add 6 to both sides.

9u = 6u + 6 + 6

3. Simplify 6u + 6 + 6 to 6u + 12.

9u = 6u + 12

4. Subtract 6u from both sides.

9u - 6u = 12

5. Simplify 9u - 6u to 3u.

3u = 12

6. Divide both sides by 3.

u = 12/3

7. Simplify 12/3 to 4.

u = 4

Answer: u = 4

1. Expand.

9u - 6 = 6u + 6

2. Add 6 to both sides.

9u = 6u + 6 + 6

3. Simplify 6u + 6 + 6 to 6u + 12.

9u = 6u + 12

4. Subtract 6u from both sides.

9u - 6u = 12

5. Simplify 9u - 6u to 3u.

3u = 12

6. Divide both sides by 3.

u = 12/3

7. Simplify 12/3 to 4.

u = 4

Which shows how to determine the volume of the pyramid?

**Answer:**

d would be correct

**Step-by-step explanation:**

A pyramid is a polyhedron formed by connecting a polygonal base and an a a p e x. The basic formula for pyramid volume is the same as for a cone: volume = (1/3) times base area times height, where height is the height from the base to the a p e x. That formula is working for any type of base polygon and oblique and right pyramids.
