Answer:

25

Explanation:

We can see that (2x+1) + (x+14) is a right angle. So, the total of those two angles should be 90.

(2x+1) + (x+14) = 90

2x + 1 + x + 14 = 90

3x + 15 = 90

3x + 15 - 15 = 90 - 15

3x = 75

3x/3 = 75/3

x = 25

x = 25

Explanation:

The two angles are complementary so we can write


(2x + 1) + (x + 14) = 90


\Rightarrow 3x + 15 =90

or


3x = 75 \Rightarrow x = (75)/(3) = 25
