Find the angle measure.<br><br> The measure of angle XYZ is
shutvik [7]

Answer:

<h3>∠XYZ = 102</h3><h3></h3>

Step-by-step explanation:

<u>1st step is to solve x from ΔWXY</u>

∠W + ∠X + ∠Y = 180

where ∠W = 5x + 2

           ∠X = 7x + 4

           ∠Y = 180 - (15x - 18)

                 = 198 - 15x

now plugin values into the equation:

5x + 2   +   7x + 4  +  198 - 15x  = 180

combine similar terms:

5x + 7x - 15x = 180 - 2 - 4 - 198

simplify:

-3x = -24

x = -24 / -3

x = 8

<u>2nd step is to substitute x = 8 into ∠XYZ</u>

∠XYZ = 15x - 18

∠XYZ = 15(8)  - 18

∠XYZ = 102

Solve for a a^2+17=42?
grandymaker [24]

We are given the following equation:

a^2+17=42

Subtract both sides by 17

a^2=25

Take the positive/negative square root of both sides

a=\pm5

This should be your answer. Let me know if you have any questions, thanks!
