If 1 inch is equal to 3 feet so you can say:
20 inches are equal to 20*3 = 60
and 19 inches is equal to 19*3 = 57
and because the school is rectangular so the area of the school is:
60* 57 = 3420 :))
i hope this is helpful
have a nice day
Answer:
Step-by-step explanation:
∠ADC = 90°
∠ADB + ∠BDC = 90
20 + ∠BDC = 90
∠BDC = 90 - 20 = 70
∠BDC = 70°
16) ∠PSR = ∠PSQ +∠QSR
= 60 + 10
= 70
18) ∠PSR = 130
∠PSQ + ∠QSR = 130
90+ ∠QSR = 130
∠QSR = 130 - 90
∠QSR = 40
19)∠ADC = ∠ADB + ∠BDC
= 120 +20
= 140
20) ∠PSR = 125
Well 2/3^3 is just 2/3*2/3*2/3 which is 2/3*2/3=4/9 then 4/9*2/3=8/27
So your answer is 8/27
.63 i mean it is not that hard
