Answer:

41°

Step-by-step explanation:

Sum of angle measures in a triangle: 180°

So,

108 + x + 5 + x - 5 = 180

Simplify.

2x + 108 = 180

Subtract 108 from both sides.

2x = 72

x = 36

Substitute x = 36 into (x + 5)

m∠A = 36 + 5 = 41

Thus, the answer is 41°

Use pythagoras theorem to find height. you get, h=4. so volume , $v= \frac{\pi r^{2}h}{3}$

u get,v= $\pi *3*4= 12 \pi$

Answer:

(4x -4)° +x° +(6x-3)° = 180°
J = 99°
K = 64°
L = 17°

Step-by-step explanation:

The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."

<h3>equation</h3>

(4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle

<h3>solution for x</h3>

11x -7 = 180 . . . . . . . divide by °, collect terms

11x = 187 . . . . . . . . add 7

x = 17 . . . . . . . . . divide by 11

<h3>angle values</h3>

m∠J = (6x -3)° = (6(17) -3)° = 99°

m∠K = (4x -4)° = (4(17) -4)° = 64°

m∠L = x° = 17°
