Because the angles are supplementary, they add to 180 degrees.
I solved this by dividing

which gives me 30 degrees.
multiply 30 by 5 gives you 150.
and 30 + 150 = 180
Answer:
The answer is A.
Step-by-step explanation:
Since it is a square we are finding the area of, we are multiplying two numbers. Which means 1/3 by the power of 2.
<h2>Answer- P=<u>18</u></h2>
Step-by-step explanation:
Greetings !
Firstly, find the class-midpoints (X) to solve for the mean.
Thus, mid points of each classes are

Solve, for <em>p</em><em> </em>using mean grouped data formula

multiply each values add them and solve for <em>p</em><em>.</em>
<em>
</em>
make a cross multiplication

subtract 270 from both sides

subtract <em>24</em><em>p</em><em> </em>from both sides

Answer:
2.18 I think this is the answer sorry if it's not-
Answer:

Step-by-step explanation:
sum of interior angles in a triangle is 180 degree
interior angles are (5x+3y)∘,(3x+20)∘, and (10y+30)
add all the angles and make it equal to 180

combine like terms


subtract 50 from both sides
