Need help on this too

Solve for x

x=-6

Step-by-step explanation:

first we want to find the missing angle inside of the triangle. To do that we subtract the angles that are given by 180 because all of the angles in a triangle should add up to equal 180

180-64-27=89

the angles outside of the triangle and the angle that equal 89 should also add up to equal 180 so we setup an equation

89+97+x=180

step 1 combine like terms

186+x=180 step 2 subtract each side by 186

x=-6 hope this helps (;

good bye

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:
