Answer:
The angles are adjacent. x=20
Step-by-step explanation:
The angles should add up to 180 because they are supplementary.
7x+x+20=180
8x+20=180
180-20=160
8x=160
x=20
Replace the x in the expression for f(x) by the expression for g(x)
= 6 (5x - 1) + 10
= 30x - 6 + 10
= 30x + 4 Answer
Answer:
108m
Step-by-step explanation:
Hello, to find the height of the bigger triangle, you take the width of the bigger triangle and divide by the width of the smaller triangle like this:
72/0.8=90
Then, you take 90 and you multiply it by the height of the smaller triangle like this:
1.2 x 90= 108
So the height of the bigger triangle is 108m.
