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°
Not really, is this a rhetorical question? lol
Answer:
x ≤ 10
Step-by-step explanation:
The second one is a perfect square trinomial
X^2+16x+64
Answer:
it will be 49 because u will add four because 37+4=41 41+4=45. 45+4= 49
