Answer:
1. 68 , 2. 22, 3. 63, 4. 27, 5. 22
Step-by-step 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
