Answer:
D
Step-by-step explanation:
Sum the three angle of triangle = 180
x + 53 + 60 = 180
x + 113 = 180
x = 180 - 113
x = 67
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for x
x = 180° - (53 + 60)° = 180° - 113° = 67° → D
Answer: 47?
42,000 x .60 (3/5)=25200
42,000-25,200= 16,800
-6
13+(-19) (distribute "+" sign into parentheses)
= 13-19
= -6
