Answer:
x = 437.3 ft
Step-by-step explanation:
The angle at the top of the triangle = 90° - 29° = 61°
Using the sine ratio in the right triangle
sin61° = 
= 
Multiply both sides by 500
500 × sin61° = x, hence
x ≈ 437.3
Answer:
y=y
Step-by-step explanation:
Assuming the question is to simplify:
Add 3x and 2x on the left side
5x+2y+2=3x+2x+2
Add 3x and 2x on the right side
5x+2y+2=5x+2y+2
Move all terms containing x to the left side of the equation
Subtract 5x from both side
5x+2y+2-5x=2y+2
x cancel out
2y+2=2y+2
Moving the constant to the right side of the equation
2y=-2+2y+2
Simplify
2y=2y
Divide 2
y=y
Step-by-step explanation:
There are 10 + 20 = 30 total students in the class.
Total marks for the class = 60 * 30 = 1800.
Total marks for the girls = 54 * 20 = 1080.
=> Total marks for the boys = 1800 - 1080 = 720.
Mean mark for the boys = 720 / 10 = 72.
