Answer:
<h2>m

6 = 68°</h2>
Step-by-step explanation:
From the question all the angles are on a a straight line which means the sum of their angles is 180 and one of the angles is 90°
So to find m
6 , add
m
5 and 90 and subtract the result from 180°
That's
m
5 + m
6 + 90 = 180
m
6 = 180 - 90 - m
5
m
6 = 180 - 90 - 22
We have the final answer as
<h3>m

6 = 68°</h3>

Answer:
The answer is option 1.
Step-by-step explanation:
In order to solve x, you have to make x the subject, by multiplying each sides by 5, to get rid of 5 on the left side.



Y = cot2(sinФ)
dy/dФ = d/dФcot2(sinФ)
dy/dФ = -cosec²2(sinФ) d/dФ2(sinФ)
dy/dФ = -cosec²2(sinФ) 2cosФ
dy/dФ =-2[cosФ][cosec²2(sinФ)]
