Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
Answer:
9
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
The three angles add to a straight line which is 180 degrees
20 + 6x-2 + 90 = 180
Combine like terms
108 + 6x = 180
Subtract 108 from each side
108+6x-108 = 180-108
6x =72
Divide each side by 6
6x/6 = 72/6
x=12
Let us assume the gas bill of Paul in February = x dollars
Then
Electric bill of Paul for the month of February = (x/2) + 3
Amount of Electricity bill of Paul for the month of February = $92
then we can write the equation as
(x/2) + 3 = 92
x/2 = 92 - 3
x/2 = 89
x = 89 * 2
= 178 dollars
So the gas bill of Paul in February is $178. I hope this is the answer you were looking for.
