Use the diagram below to answer part a-c

A) <HJL and <LJK are supplementary angles so sum = 180

26x - 7 + 10x + 7 = 180

36x = 180

x = 5

B)

<HJL = 26(5) - 7 = 123°

<LJK = 10(5) + 7 = 57°

check the reply above.

29 is the correct answer

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
