I got this right on my test
Answer:
x = 2
Step-by-step explanation:
5x + 3 = 7x - 1
Subtract 3 to both sides
5x = 7x - 4
Subtract 7x to both sides
-2x = -4
Divide by -2 to both sides.
x = 2
Hope this helps and pls do mark me brainliest if you can:)
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
