Question

b) From the given figure determine the value of y

Answer 1

Answer:

here's your answer

Step-by-step explanation:

we know that a reflex angle sum is 360° so we will add all the angels

5y+5y+2y=360°

12y=360°

y=30°

Answer 2

Answer:

2 diagonal lines create an angle of 90°

so using line A and B

2y+90°+5y=180°

90°+7y=180°

180°-90°=7y

90°=7y

90/7=y
