Help the questions c and d please!!

Answer 1

17

Explanation:

Answer 2

c is 45 and d is 60

Explanation:

c has one right angle (90) so 90 + a + a =180. 90 +2a = 180 so 2a = 180-90 (90).

90/2 is 45

therefore a = 45

d has all sides equal. so divide 180 (the total angle in a triangle) by 3 =60
