44 you should subtract 80 and 36 then the answer will be 44
we get x by setting up a proportion.
=
then we cross multiply.
12(5x−1) = 21(2x+2)
60x − 12 = 42x + 42
18x − 12 = 42
18x = 54
<u>x = 3.</u>
plug in 3 for x for <u>LB</u>, which is <u>2x + 2.</u>
<u>LB </u>= 2(3) + 2 = 8
plug in 3 for x for <u>BG</u>, which is <u>5x - 1.</u>
<u>BG </u>= 5(3) - 1 = 14

Answer: The amswer is D because -1 + 1 = 0
This is an isosceles triangle: y is the same value as 59:
59 = y
(and if it asks later, 180 - 59 - 59 = x, x = 62)
mark me as brainliest pls :)
<u>Let's take this problem step-by-step</u>:
<u>The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'</u>
⇒ is on a straight line
⇒ sum of angle measure = 180 degrees
<u>Now we know:</u>
⇒ sum of all angles in a triangle ⇒ 180°
<u>Let's put that in equation form and solve:</u>
<u>Answer: 21°</u>
<u></u>
Hope that helps!
