Question

Find the measure of angle b

Answer 1

answer: 65°
explanation: 115°+115°= 230°
360°-230°=130°
130° divided by 2= 65°

Answer 2

b = 65°

Explanation:

Now we have to,

→ find the required value of b.

Forming the equation,

→ 115° + b = 180°

Then the value of angle b is,

→ 115° + b = 180°

→ b = 180° - 115°

→ [ b = 65° ]

Hence, the value of b is 65°.
