Answer:
Step-by-step explanation:
56 degree + 62 degree = 180 degree
118 degree = 180 degree
180 degree - 118 degree
= 62 degree
62 degrees
the inside angles of a triangle always equal 180 degrees when added, so i just subtracted 56 and 62 from 180, also, the triangle is isosceles, which has 2 angles of equal value, so the unknown angle had to be equal to 62
120
supplementary equal up 180
the factor for x^2 + 5x - 24 is
(x + 8)
