Solve for x.<br><br> 0.5x + 78.2 = 287

vladimir2022 [97]

0.5x + 78.2 = 287
-78.2 -78.2

subtract 78.2 on both sides you will then get 0.5x = 208.8 you will then divide by 0.5 and the answer is x = 417.6

Plz Help!!! I need this Asap. Plz give an explanation and no guessing only answer if you know.

borishaifa [10]

Answer:

Step-by-step explanation:

AB = AC

So, it is a isosceles triangle.

<B = <C = 65°

Sum of angles of triangle = 180°

< A + < B + <C = 180°

plug the values:

X + 65° + 65° = 180°

Calculate the sum

X + 130° = 180°

Move constant to R.H.S and change its sign

x = 180° - 130°

Calculate the difference

X = 50°

Hope this helps...

Good luck on your assignment...
