Answer:
38.667°
Step-by-step explanation:
the total sum of 3 angles in a triangle is 180
in triangle PQR this means:
P+Q+R = 180
so:
64+x+2x=180
64+3x=180
3x=116
x=116/3=38.667
So Q=X=38.667

Answer:
Part a) The area of the actual floor is 
Part b) The ratio of the area in the drawing to the actual area is 
Step-by-step explanation:
we know that
The scale drawing is 
step 1
Find the dimensions of the square on a scale drawing
The area of a square is equal to

where
b is the length side of the square

so


step 2
Find the dimensions of the actual floor
Divide the length of the floor on the drawing by the scale drawing

step 3
Find the area of the actual floor
The area of a square is equal to

substitute

step 4
Find the ratio of the area in the drawing to the actual area

Simplify
Divide by 64 both numerator and denominator
