Math help please What is the length of side BC of the triangle?

1 answer:

3 0

BC is 28 units long.

To find x, write the equation 4x - 7 = 2x + 7, as sides AC and AB are equal because the triangle is isosceles. The triangle is isosceles due to the base angles theorem. Once we get x, which is 7, we need to substitute it into the equation of BC. We then get 4(7), which equals 28 units.

w=37

2w+w+69= 180 knowing that all triangles add up to 180 form an equation

3w+69=180 combine like terms and subtract 69 from both sides

3w=111 divide by 3 from both sides

w=37
