Question

Please help me find the angle of these, Also show work if possible so i can use it for future lessons.

Answer 1

1. 68 , 2. 22, 3. 63, 4. 27, 5. 22

Explanation:

Angles in a triangle add up to 180 degrees

180 - (68+ 90) = 22

Then to work out angle 1 you do 90 - 22 = 68

Angles on a straight line add up to 180 degrees

To find the angle next to 131 degrees

you do 180 - 131 = 49 degrees

49 + 68 + ? = 180

? = 63

90 - 63 = 26

90 - 68 = 22
