y+ (5x-10)= 180 º

Due to the lines are parallels

$\alpha=\beta$

So then

(5x-10)= (x+86)

5x - x = 86 + 10

4x = 96

x = 24

__________________

Checking

(5x-10= 5*24-10= 110º

(x+86) = 24+ 86= 110º

__________________________

y+ (5x-10)= 180 º

y+ 110º = 180 º

y= 180-110º

y= 70º

Find the value of BC. HELP PLEASE!!

Masteriza [31]

It's an equilateral triangle, therefore

AB = BC = BA

We have the equation:

$\dfrac{3}{2}x-12=\dfrac{1}{2}x-2\qquad\text{multiply both sides by 2}\\\\3x-24=1x-4\qquad\text{add 24 to both sides}\\\\3x=x+20\qquad\text{subtract x from both sides}\\\\2x=20\qquad\text{divide both sides by 2}\\\\x=10$

$BC=BA\to BC=\dfrac{1}{2}(10)-2=5-2=3$

<h3>Answer: BC = 3</h3>
