1. find the value of x.

(there is a triangle abc with angle c = 60°, side ac = 4x, side bc = 40. also, there are some handwritten notes and a yield sign image with some text about signs notify slow down and yielding vehicles first. and 4x + 2 near the yield sign.)

Explanation:

Step1: Assume triangle is equilateral

If triangle ABC is equilateral, all sides equal: $4x = 40$.

Step2: Solve for x

$x = \frac{40}{4} = 10$.

Answer:

10
