The sum of the angles of a triangle is equal to 180 degrees.
We then have the following equation:
G + H + I = 180
Substituting values:
(2x + 5) + (6x - 10) + (x + 5) = 180
Clearing x we have:
(2x + 6x + x) + (5-10 + 5) = 180
9x + 0 = 180
9x = 180
x = 180/9
x = 20
Then, for the angle H we have:
H = (6x - 10) °
Substituting:
H = (6 (20) - 10) °
H = (120 - 10) °
H = 110 °
Answer:
the current measurement of angle H is:
H = 110 °
A) W + Y = 29
B) 11.95 W + 11.50 Y = 338.90
Multiply equation A by -11.5
A) -11.5 W + -11.50Y = -333.50 then add to B)
B) 11.95 W + 11.50 Y = 338.90
.45 W = 5.4
W = 12 and so
Y = 17
1) Answer: x = 9
<u>Step-by-step explanation:</u>
Same Side Interior Angles are supplementary
15 + 5x + 14x - 6 = 180
19x + 9 = 180
19x = 171
x = 9

2) Answer: x = 9
<u>Step-by-step explanation:</u>
Corresponding Angles are congruent
13x - 7 = 11x + 11
2x = 18
x = 9
***************************************************************
3) Answer: x = -10
<u>Step-by-step explanation:</u>
Alternating Interior Angles are congruent
90 = x + 100
-10 = x

Step-by-step explanation:
<u>Operations with Fractions</u>
Mark sold
gallons of lemonade.
Regan sold
as much lemonade as Mark
We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:

Now we multiply:
