Answer:
D
Step-by-step explanation:
x + 5 + 3x + C = 180 All triangles have 180 degrees.
4x + 5 + C = 180
But C must be equal to 3x. Notice the markings on the lets of the triangle.
4x + 5 + 3x = 180
7x + 5 = 180 Subtract 5 from both sides
7x = 180 - 5
7x = 175
x = 25
But angle C = 3x
C = 3*25
C = 75
Explanation : % is the symbol for percentage. It means out of 100. 75% means 75 out of 100 which is represented as 75/100.
G=3
If you multiply out x+7 and x-4 you get <span>x^2+3x-28
