angle 1 and angle 2 form a linear pair. If measure angle 1 =18x-1 and measure angle 2=23x+17, find measure angle 2.
finlep [7]
Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52
Hope this helps!

Given data in the question:-      

(x+7)2=121

We have to find the value of x.

Solution:-        

(x+7)2=121\\=>2x+14=121\\=>2x=121-14\\=>2x=107\\=>x=107/2\\=>x=53.5\\

Hence the answer is 53.5
