The answer is (2,1). 2*2=4 and 9*1=9. 9+4=13
Answer: 52.5 units squared
Step-by-step explanation:
The formula to find the area of a trapezoid is, (base1 + base2)/2 * height
So you find out which variable is which
Base 1 = 4
Base 2 = 3
Height = 15
Then plug it into the formula,
(4+3)/2 * 15
Then solve the order of operations
7/2 * 15
3.5 * 15
52.5 is the answer
Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
