Answer:
45 minutes
Step-by-step explanation:
Answer:
C. 52°
Step-by-step explanation:
In ∆CAB, m<A = right angle = 90°
m<B = 38°
m<C + m<A + m<B = 180° (sum of ∆)
m<C + 90° + 38° = 180° (substitution)
m<C + 128 = 180
m<C = 180 - 128 (subtraction property of equality)
m<C = 52°
Answer:
102
Step-by-step explanation:
Let the unknown measure be x
So all the angles add up to 180
therefore,
13 + 65 + x = 180
78 + x = 180
x = 180 - 78
x = 102
