∠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°

Answer: ?????
Step-by-step explanation: Is it doable? 23 - 4 = 19
Answer:
The answer is A: -3<9 and -3<9
Step-by-step explanation:
because -3 is less than 9
If given a line in the slope-intercept form
y=mx+b
m is the slope and b is they y-intercept
The area of the whole figure is 92.1
the area of the rectangle is 78
the area of the half circle is 14.13
add them together, you get 92.1
hope this helps :D
