Answer:
53
Step-by-step explanation:
Sol'n
Let the remaining angle of a triangle be x.
x+71+56=180 (Sum of angles of a triangle is 180°)
or, x+127=180
or, x=180-127
.:, x=53°
.:, The measure of third angle is 53°
Answer:
Option C
Step-by-step explanation:

![\sf log_w \ \dfrac{(x^{2}-6)^4}{\sqrt[3]{x^2+8} }=log_w \ (x^2-6)^4 - log_w(x^2+8)^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csf%20log_w%20%5C%20%5Cdfrac%7B%28x%5E%7B2%7D-6%29%5E4%7D%7B%5Csqrt%5B3%5D%7Bx%5E2%2B8%7D%20%7D%3Dlog_w%20%5C%20%28x%5E2-6%29%5E4%20-%20log_w%28x%5E2%2B8%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)

82+2x=180
2x=98
x=49
answer is x=49
