In ΔTUV, m∠T = (10x+14), m∠U = (x-7), and m∠V = (2x+4). Find m∠U.

6 degrees

Step-by-step explanation:

In ΔTUV, m∠T = (10x+14), m∠U = (x-7), and m∠V = (2x+4). Find m∠U.

We know that the sum of all the angles is 180

Hence

m∠T + m∠U + m∠V = 180

(10x+14) + (x-7) + (2x+4) = 180

10x+14+x-7+2x+4 = 180

13x+11=180

13x=169

x=13

m∠U = (x-7)

=13-7=6
