Answer:
Im not sure i love fractions lol
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
x² + 3x - 10
p + q needs to equal the b-value.
Since b = 3, then the sum of p = -2 and q = 5 works.
⇒ (x - 2)(x + 5)
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°
