Which of the following statements are true? Select all that apply. ((2x + 10 (x + 15) B A. (4x + 16)° = 180° B. Xº = 49° C. MZA= 99° D. From smallest to largest: ZB, ZC, ZA

Answer: A and D

Step-by-step explanation:

2x + 1 + x + x + 15 = 180
4x + 16 = 180 ( Choice A )
4x = 180 - 16
4x = 164
x = 41

Angle A = 2(41) + 1 = 83°
Angle B = 41°
Angle C = 41 + 15 = 56°

=> Angle B < Angle C < Angle A ( Choice D )
