Answer:
x=-2
Step-by-step explanation:
Since it is an equilateral triangle (note the little lines across the legs of corner 2) the other angle must be 69° as well.
That leaves 180-69-69 = 42 for ∠2.
So x + 44 = 42 => x = 42-44 = -2.
3(n+2) ← algebraic expression

An easier way of doing it mentally is 3 x 25 which is 75 and then 1 x 25 which is 25
Answer:
39
Step-by-step explanation:
Total interior angle of a triangle equal to 180. [180-102]/2
