This is what my math teacher had me write down!
Answer:x<-18
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
-1/2x+3>12
Step 2: Subtract 3 from both sides.
-1/2x+3-3>12-3
-1/2x>9
Step 3: Multiply both sides by 2/(-1).
(2/-1)*(-1/2x)>(2/-1x)*(-1/2x)
X<-18
:D
I can't seem to find the measure because it always when trying to find x (verticla angle) turns into a decimal answer. So I'm hoping that the diagram could help you find your answer.
∠R = 100° , ∠S = 40° and ∠T = 40°
<u>Step-by-step explanation:</u>
In a triangle, sum of all the angles in a triangle is equal to 180 degrees.
In Δ RST,
∠R + ∠S + ∠T = 180°
It is given that,
∠S = ∠T
∠R = 2∠S + 20
So plugin these values in the above equation, we will get,
2∠S + 20 + ∠S+ ∠S = 180
4∠S = 180 - 20
∠S = 160/ 4 = 40
∠R = 2× 40 + 20 = 80 + 20 = 100°
∠S = ∠T = 40°
