Help, please
Elanso [62]

Answer: 10.5 is my guess

Step-by-step explanation:

1. 30% = 8.4

   100      x

cross multiply

30(x) = 840

divide both sides by 30 = 28

2. 37.5% = y

     100     28

cross multiply

1050 = 100y

divide both sides by 100 = 10.5

In a parallelogram PQRS, if angle P = (2x+25) degrees and angle Q = (3x-5) degrees, then write the measures of angle S and angle
krek1111 [17]

Consecutive angles of a parallelogram are supplementary, so:

2x+25+3x-5=180\\5x+20=180\\5x=160\\x=32

This means m\angle P=2(32)+25=89^{\circ} and that m\angle Q=3(32)-5=91^{\circ}.

Since opposite angles of a parallelogram are congruent,

\boxed{m\angle S=91^{\circ}, m \angle R=89^{\circ}}
