Question

What is the value for x?

Answer 1

Answer:

Step-by-step explanation:

Note that it is a triangle's measurement = 180°

You are solving for x. Set all the angles = 180°

73 + 8x + 4  + 8y - 7 = 180

Simplify. Combine like terms

73 + 4 - 7 + 8x + 8y = 180

70 + 8x + 8y = 180

Solve for x. Subtract 8y and 70 from both sides

8x + 8y (-8y) + 70 (-70) = 180 (-8y) - (70)

8x = 180 - 70 - 8y

8x = 110 - 8y

Isolate the x. Divide 8 from both sides

(8x)/8 = (110 - 8y)/8

x = 13.75 - y

x = 13.75 - y is your equation you will use to solve for x when you know what y is.

Answer 2

Answer:

x = 5 and y = 12

Step-by-step explanation:

Angle A: 73 degrees.

Angle B: (6x + 4) = ((6 * 5) + 4) = 30 + 4 = 34 degrees.

Angle C: (8y - 7) = ((8 * 12) - 7) = 96 - 7 = 89 degrees.

Aall the angles of a triangle should add up to 180 degrees!

73 + 89 + 34 = 180
