Question

please solve step by step​

Answer 1

a=60 and 2a=120

Step-by-step explanation:

there are 2 90degree angles in figure

so 90+90+a+2a=360(sum of all angles)

180+3a=360

3a=360-180

3a=180

a=180/3

a=60

2a=2×60=120

for verification add all four angles if sum is 360 answer is correct

hope it helps you......
