Answer:
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
Answer: the numbers can be 16 and 9, 6 and 24 or other factors of 144
1.) add 9 and 5 which is 14-6x
0.4 is

and that simplified is

because you take the GCF or Greatest Common Factor, which is two, and divide both parts of the fraction taking

and turning it into
923/5000
If you put it in your calculator
