Answer:
Step-by-step explanation:
In a given triangle, the sum of every angle is always 
. Here, we are given a right angle (
), as well as another 
angle. Simply subtracting from 180 will give us the answer.
-3x+14=4x-7 = x=3
The answer is x=3
Answer
(3x-3)
Step-by-step explanation:
We know that
Applying the law of cosines
c²=a²+b²-2*a*b*cos
C------> cos C=[a²+b²-c²]/[2*a*b]
in this problem
a=7.6 in
b=8.6 in
c=7.4 in
C=angle V
cos C=[7.6²+8.6²-7.4²]/[2*7.6*8.6]----> 0.5887
C=arc cos (0.5887)--------> C=53.93°-------> C=53.9°
the answer is
angle V is 53.9°
