x - 16 = 47 <em>add 16 to both sides</em>
x - 16 + 16 = 47 + 16
x = 63
S = s(s +2h) = 24(24 +2*20) = 1536 . . . . square inches
Selection C is appropriate.
Answer:
35 degrees
Step-by-step explanation:
The angles in a triangle and a straight line add up to 180 degrees.
So adding the angles together:
BCD + BCA = 180
75 + BCA = 180
BCA = 115
Then,
BCA + BAC + ABC = 180
115 + 40 + ABC = 180
Therefore,
ABC = 35 degrees
3 because it is 9 units but dilated by 3. So 9/3 = 3
