Answer:
Step-by-step explanation:
We need x first.
AB = DE
12 = 3x -3
4 = x -1 . . . . . divide by 3
5 = x
Now, we can find y.
∠C = ∠F
7x +y = 55
y = 55 -7x = 55 -7(5)
y = 20

1/x^15 (1st choice)
#3
c^15 (2nd choice)
#4
x^10 / m^3 (last choice)
#5
x^12y^8 (1st choice)
#6
1 / 8y^12 (3rd choice)
#7
r^10 s^5 (last choice)
#8
x^4 / y^6 (last choice)
#9
(b^2)^4 = b^8
answer is 4 (2nd choice)
Answer:
(c) 135°
Step-by-step explanation:
Angles 5 and 8 form a linear pair, which means they are supplementary: their measures total 180°.
∠8 = 180° -∠5 = 180° -45°
∠8 = 135°
