Answer:
Step-by-step explanation:
A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12
Divide the figure into 3 shapes
top square
middle trapezoid
bottom rectangle
so
Area of figure
= (10x10) + 1/2(8 + 14)(4) + (20 x 6)
= 100 + 44 + 120
= 264
answer
264 cm^2
X = 33 °
Since PQS forms a 90 degree angle, subtract 57 (from PQR) to get RQS.
90-57=33
