What is the measure of Zc

maks197457 [2]

Answer: 56 degrees

Step-by-step explanation:

We know that angle between b and c is 90 degrees. Because there is a line dividing angles a and b from 124 and c, we also know that each side is 180 degrees (a and b add to 180, and 124 and c add to 180).

124 and c are supplementary angles. We can represent this in an equation to solve for c:

$124 + c = 180\\\\c = 56$

(x -1) = 26 = -4x A. -7 5/7 B. 8 C. -7 D. -5

Volgvan

Based on the answer choices, we suspect you intend
.. (x -1) +26 = -4x

This simplifies to
.. x +25 = -4x
.. 25 = -5x . . . . . subtract x
.. -5 = x . . . . . . . divide by the coefficient of x

Selection D appears to be appropriate for the question we think you asked.
