Solve for z.
2 + 8 - z = -24

Z=34

Step-by-step explanation:

z = 34

Step-by-step explanation:

Given

2 + 8 - z = -24

Combine Like Terms-

10 - z = -24

Rearrange Terms-

-z + 10 = -24

Subtract 10 from both sides

-z + 10 - 10 = -24 -10

Simplify

-z = -34

Divide -1 from both sides

-z/-1 = -34/-1

Answer-

z = 34

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
