Answer:
9x - 8
Step-by-step explanation:
the perimeter is the sum of the sides, hence
perimeter = 5x - 2 + 3x + 4 + x - 10 ( collect like terms )
= 9x - 8 ← polynomial of degree 1
X+79=98 (subtract 79 to isolate x)
X=19 so it is false
Answer:
62
Step-by-step explanation:
the triangles angles always add up to 180 degrees
66+52=118
180-118=62
hope this helps :) have a nice day !!
