Answer:
The answer is sinA + cosA
Step-by-step explanation:
3 sinA – cosA – 2 sinA + 2 cosA
3 sinA – 2 sinA – cosA + 2 cosA
sinA + cosA
Thus, The answer is sinA + cosA

Answer:
The length of wooden board = 9.4648 feet.
Step-by-step explanation:
The wooden board makes a Right triangle with the building in which we have wooden board as hypotenuse, building as opposite side, and ground as adjacent side, the angle of elevation is 65 degrees.
Given adjacent side = 4 feet and elevation angle = 65 degrees.
We can use cosine formula in right triangle as follows:-
Cos(65°) = Adjacent / Hypotenuse
cos(65°) = 4 / Hypotenuse
Hypotenuse = 4 / cos(65°)
Hypotenuse = 9.464806333 feet.
Hence, the length of wooden board = 9.4648 feet.

Answer:
Step-by-step explanation:
As we can see that Line WL is a straight line that the angles that make up it like Angle HJW and Angle GJH and Angle LJG all equal to 180 degrees
Angle HJW = 18 degrees
ANGLE GLH = 90 degrees (we know that because there is a little square)
Angle LJG = 9x
Now lets set up the equation:
Angle HJW + Angle GLH + ANGLE LJG = 180 degrees
18 + 90 + 9x = 180
108 + 9x = 180
9x = 72
x = 8
So x = 8
