PLEASE HELP :) 20 POINTS FOR IT IF U JUST ANSWER LIKE IDK OR SUM IMMA REPORT

nalin [4]

Answer:

BC = $1.8$

Step-by-step explanation:

∆ABC is an equilateral ∆ because all three angles are equal. Therefore, all its sides would be equal also. This means AB = BC = AC

Thus, let's find the value of x.

$\frac{7}{4}x - 1 = \frac{9}{3}x - 3$

Collect like terms

$\frac{7}{4}x - \frac{9}{3}x = 1 - 3$

$\frac{7x}{4} - 3x = -2$

$\frac{7x - 12x}{4} = -2$

$\frac{-5x}{4} = -2$

Multiply both sides by 4

$\frac{-5x}{4}*4 = -2*4$

$-5x = -8$

Divide both sides by -5

$x = \frac{8}{5}$

AB = BC = AC

Therefore,

BC = $\frac{7}{4}x - 1$

Plug in the value of x

BC = $\frac{7}{4}*\frac{8}{5} - 1$

BC = $\frac{56}{20} - 1$

BC = $2.8 - 1$

BC = $1.8$
