In triangle XYZ, m∠Z > m∠X + m∠Y. Which must be true about △XYZ? m∠X + m∠Z 90°
∠X and∠Y are complementary
m∠X + m∠Y < 90°

m < X + m < Y < 90

Step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

it is not that hard all u have to do is plot the graph
