Answer:
.
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:
B = 100
Step-by-step explanation:
25 + .05x = 20 + .10x
5 = .05x
100 = x
