The angles measures x and 4x are complementary angles. Which is the value of x?
Hitman42 [59]

<u>Answer:</u>

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

<u>Solution:</u>

Given, two angles are x and 4x

We have to find the value of above given x  

We are also given that, given two angles are complementary angles for each other

So, we know that, <em>sum of any two complementary angles will always be equal to 180 degrees </em> 

Then, in the problem given,

x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
