Hi there! :)
Answer:
D. 1980°
Find the sum of the measure of a 13-sided polygon using the formula:
Sum = 180(n-2), where n = number of sides
Therefore:
S = 180(13 - 2)
S = 180(11)
S = 1980°
Answer:
x = 30
2x =60
Step-by-step explanation:
the angle is a right angle- so that means it’s a 90 degree angle
so let’s set up an equation..
We get 90 degrees when we add 2x Plus x
So 2x + x = 90
then, 3x = 90
x= 30
you Can check your Answer by:
Do 2 times 30 = 60
and then 60+ 30
you will Get 90

Answer:
They are shown together to find units of 4 total
4 (j/ total + s/total )
= 4 (1/4 + 3/4)
= 4/4 + 12/4
= 4 cups total
Then show letters and work out for j + s
4(j/3 + 3/4) = 4
4j/3 + 12/4 = 4
4j/3 + 3 = 4
4j/3 = 4-3
4j/3= 1
j = 1/3 s = 3/4 * 4 = 3
You would rearrange 4 within the brackets to find total
3 (1/3 + 4t) = 4
1 + 12t = 4
12t = 4-1
12t = 3
t = 12/3 of the total
t = 4
