Answer:
Step-by-step explanation:
1) a = x - 5
a) z = y + 5
b) z = y - 3
c) z = 6y
d) z = 6y - 2
e) z = 3y + 5
If perimeter is 60 so the side is 60 ÷ 3 = 20
Now we can apply the area formula for triangles;
Answer :c
I think sorry if it’s not correct
The area is A = 42. Hope this helps
Answer:
Before solving the given trigonometric relation change everything to sines and cosines
Step-by-step explanation:
consider the given equation;
=
Multiplying the above equation on both sides by
then we get,

By using identity,
expand above equation we will get,

Then,


So the required value of the angle is
degree.
