C. 5(x+7)
Step-by-step explanation:
app it's a standard 30 60 90 triangle. there are rules for this.
x = 3
y = 6
B, that makes the six negative and not the five
Answer:
Angle A = 75°
Angle B = 75°
Angle C = 30°
Explanation:
If AC is congruent to CB, from figure given we have angle A = angle B.
Angle A = 3x + 18
Angle B = 7x - 58
Angle C = 2x - 8
We have,
3x + 18 = 7x - 58
4x = 76
x = 19
So,
Angle A = 3*19 + 18 = 75°
Angle B = 7*19 - 58 = 75°
Angle C = 2*19 - 8 = 30°
