Question

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

Answer 1

.

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
