From the figure, we can conclude that the little triangle is an isosceles triangle, the greatest angle is 90 because ∠A = 90 and they are supplementary, therefore, using the triangle sum theorem:
Answer:
Step-by-step explanation:
3a + 2 = -2n + 3p
3a = -2n + 3p - 2
a = (-2n+3p-2)/3
a = -2/3(n) + p - 2/3
