C and d are complementary. The measure of c is 4x and the measure of d is 26. What is the value of x
const2013 [10]

Answer:

The value of x is 16.    

Step-by-step explanation:

We are given the following in the question:

c and d are complementary angles.

Measure of c = 4x

Measure of d = 26

Since c and d are complementary, we can write from property of complementary:

c + d = 90

Putting values, we get,

4x + 26 =90\\4x = 90-26 = 64\\\\\Rightarrow x = \dfrac{64}{4} = 16

Thus, value of x is 16.
