Question

Find the value of y
(remember the two arches mean these angles have the same value).​

Answer 1

Answer:

The value of y is 40⁰

Step-by-step explanation:

In this sum of exterior angles in this 360⁰

So the angle of first in interior angle

x+75⁰ =180⁰

The sum of all angle of triangle is 180⁰

x=180⁰-75⁰

x=105⁰

So angle of second interior

x+67⁰ =180⁰

The sum of all angle of triangle is 180⁰

x=180-67

x=113⁰

The third interior angle is 90⁰

105⁰+113⁰+90⁰+y=360⁰

320⁰+y=360⁰

y=360-320

y=40⁰
