I really need the answer please the question 2 and 3 plz

.

Step-by-step explanation:

2.

If angle A = 4x + 12 and x is given as 15 we can say that angle A is an acute triangle because its measure is less than 90° ➡ 4 × 15 + 12 = 72°

3.

if the angle BAM is a right triangle then

4x + 22 = 90 subtract 22 from the both sides

4x = 68 divide both sides by 4

x = 17

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

so then what are you asking?
