How do you find x for this triangle?

x=5

Step-by-step explanation:

since the 2 base angles are the same, we can assume that the sides opposite to them are equal, meaning that this is an isosceles triangle:

5x-8=2x+7

3x=15

x=5

(if u need more help on how i solved for x just ask in the comments, i will try my best to help)

hope this helped a bunch, brainliest plz! :)

X=5 I hope this helps you and gives you the right answer to get it right have a great day and night where ever you are

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the correct is answer is a 9-sided polygon!
