Answer:
1) h = 92°
2) f = 40°
3) same question as #1
4) x = 16
5) A
6) y = 9
Step-by-step explanation:
1) a little hard to read but if the exterior angle measures 148° then the lower right angle in Δ is 32°; that means that h = 180-(56+32) or 92°
2) the triangle has two 45° angles so the third angle is 90°; so 'f' + 90 + 50 = 180; f = 40°
4) if angles are complementary then they add up to 90;
2x+10 + 48 = 90
2x + 58 = 90
2x = 32
x = 16
5) the sum of any two sides must be greater than the third side;
in 'a', 4+2 is not greater than 7
6) these angles are congruent because they are vertical;
11y - 36 = 63
11y = 99
y = 9
