Answer:
<h2>R = 15°</h2>
Step-by-step explanation:
Since angles R and S are supplementary angles it means that the sum of their angles add up to 180°
To find R we must first find x
To find x , add angles R and S and equate them to 180
That's
R + S = 180
80 - x + 3x - 30 = 180
2x + 50 = 180
2x = 180 - 50
2x = 130
Divide both sides by 2
x = 65°
From the question
R = 80 - x
But x = 65°
Substitute the value of x into the expression
That's
R = 80 - 65
We have the final answer as
<h3>R = 15° </h3>

Answer:
-5
Step-by-step explanation:
1) write it out:
3x-4=4x+1
2)combine like terms
Supposing that the integers are x, y and z, and that their average is 8, then
x+y+z
-------- = 8, or x + y + z = 24.
3
Let's experiment. Making up a table, we get:
x y z sum (sum MUST be 24)
5 9 10 24
4 9 11 24
3 10 11 24
2 11 11 24
1 11 12 24
1 10 13 24
1 1 22 24
Can't choose integers smaller than 1, so it appears that 22 is the largest possible integer that could be one of x, y and z.
