Sum of the angles of the trapezoid (quadrilateral) add up to 360°, so based on available information
mâ A + mâ B + mâ C + mâ D = 360° relates to mâ A + 25° + 155°
+ 117°.=360°
So, mâ A = 360° - (25°+155°+117°)
mâ A = 360° - 297°
mâ A = 63°

Answer:
Number of month in first gym = 7
Number of month in second gym = 5
Step-by-step explanation:
Given:
First gym member ship cost = $75 per month
Second gym member ship cost = $50 per month
Total spending = $775
Computation:
Number of month in first gym = a
Number of month in second gym = b
So
a + b = 12....eq1
75a + 50b = 775 ....eq2
From eq 1 and 2
a = 7 month
b = 5 month
Number of month in first gym = 7
Number of month in second gym = 5
When 36 people are seated the room is 2/3 full.
So for 1/3 , 18 people are needed
It will be 3/3 full if 54 people are present
So there can be 54 people in total
Now for the room to be 1/2 full , people will be 1/2 x 54 = 27 people
