Answer 1

Step-by-step explanation:

have a nyc day ahead..........

Answer 2

x = 30°

In ∆ABC

Given : A= 40, B=B, C=90

A+B+C=180

40+B+90=189

B = 180 - (40+90)

= 180 - 130 = 50

In ∆BED

Given : E=100, B=50, D=x°

E+B+D = 180

100+50+D = 180

D = 180 - (100+50)

= 180-150 = 30

Angle D = x° = 30° ✓✓✓
