Answer:
Answer is x=328 .
Step-by-step explanation:
solution= (4x-16)^1/2=36
squaring both sides we get
4x-16=129
4x=1296+16
x=(1296+16)/4
x=328 .
We know that sin(a-b) = sina.cosb - cosa.sinb
if a=70 & b=10 the sin(70-10) = sin(60) = √3/2
Sin70cos10-cos70sin10 = sin60 = √3/2
2.5E-2 or 2.5x10^-2
Hope this can help you!
