Question

Maths angles- please help asap

Answer 1

Answer:

4x + 5x = 180

because of interior angle

hence, 9x = 180

x = 180/9

x = 20

one angle = 20*4 = 80

another angle = 20*5 = 100

hope it helps

Answer 2

Answer:

x = 20

Step-by-step explanation:

These angles are same-side supplementary, therefore they add up to 180°.

$4x + 5x = 180 \\ 9x = 180 \\ x = 20$
