Answer:
7.06
Step-by-step explanation:
This triangle can be solved a couple of ways. In the end, they amount to the same thing.
1) The area is ...
A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base
Using GE as the base, the height (DF) is ...
A = (1/2)(17)(DF)
2(60)/17 = DF = 120/17
DF ≈ 7.06
__
2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...
(long side)/(hypotenuse) = DE/GE = DF/DG
DF = DG(DE/GE) = 8(15/17) = 120/17
DF ≈ 7.06
Answer:
x=−16
Step-by-step explanation:
-2(2x+5)-3=-3(x-1)
distribute -2 into (2x+5) and -3 into (x-1)
-4x-10-3=-3x+3
combine like terms
-4x-13=-3x+3
add -4x on both sides
-13=-3x+4x+3
combine like terms
-13=x+3
subtract 3 on both sides
-16=x
