Answer:
The width of the window should be
and the height of the window should be 
Step-by-step explanation:
we know that
The circumference of a semicircle (window) is equal to

we have that


substitute and solve for r


so
the width of the window is equal to the diameter of the semicircle
so
The width of the window should be
and the height of the window should be 
400-5x greater than or equal to 250
-400. -400
———————————————————-
-5x greater than or equal to -250
——. ——
-5. -5
X is less than or equal to 50
*sorry no greater than and equal to key so...
Answer: x = 11 degrees
Step by step explanation:
Triangle rule states that all angles of a trundle must equal to 180 degrees. So we have two known angles, therefore we can subtract them from the 180 degree total.
180-109-43
=28
Now to solve for x we have the equation
4x-16=28
We add 16 to both sides to isolate x
4x=44
Now we divide each side by 4 to get rid of the coefficient
x=11
Answer:
Answer is B. 36 degrees
Step-by-step explanation:
From the diagram,
angle WBY = 2 × angle WXY
angle WBY = 72°
angle WXY =
