Question

plzzz answer this question​

Answer 1

Answer:

DAB = 50°

DAC = 130°

Step-by-step explanation:

From figure

DAC and DAB are supplementary angles I. e. their sum is 180°

5x + 30 + 2x + 10 = 180°

7x + 40 = 180

7x = 140

x = 20 °

DAB = 2x + 10

= 2 × 20 + 10

= 40 + 10

= 50°

DAC = 5x + 30

= 5 × 20 + 30

= 100 + 30

= 130°

THANKS

Answer 2

Answer:

5x+30+2x+10=180. (l.p)

7x+40=180

7x=180-40

x=140/7

x=20

angle DAB =130°

angle DAB=50°
