5x= one angle measure
7x= second angle measure
120°= third angle
Triangles equal 180°. Add the angles above to total 180°. Find x to find two two unknown angles.
5x + 7x + 120°= 180°
combine like values
12x + 120= 180
subtract 120 from both sides
12x= 60
divide both sides by 12
x= 5
ONE ANGLE MEASURE
5x= 5(5)= 25°
SECOND ANGLE MEASURE
7x= 7(5)= 35°
CHECK:
25° + 35° + 120°= 180°
180°= 180°
ANSWER: The measures of the two angles are 25° and 35°.
Hope this helps! :)
In mathematics, mean average means to take the sum of all the numbers and divide the sum by the number of elements in the set.
Add up the numbers.
<span>21 + 23 + 25 + 25 + 26 + 28 + 28 + 28 + 31 + 33 = 268
Divide by the number of elements in the set. Which is 10.
268 / 10 = 26.8
So, the answer to this question is 26.8</span>
Problem 13
10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get
10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q
so we get the original expression again. Here 10 is the GCF of the two terms.
--------------------------------------------------------------
Plug p = 1 and q = 2 into the factored form
10*(p+q) = 10*(1+2) = 10*(3) = 30
As a check, let's plug those p,q values into the original expression
10*p+10*q = 10*1+10*2 = 10+20 = 30
We get the same output of 30
The answer is for question 12, x = -9.3333333
To answer this we just need to set up a equation:-
895 - 669 - 100 = 126.
SO, after these transactions you will have $126 left.
Hope I helped ya!!
