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

52m^2= 2[(x-5)+(x)]. 52m^2= 2(2x-5). 52m^2=4x-10
Answer:
x = 3
Step-by-step explanation:
4x + 50 + 28 = 90
4x + 78 = 90
4x = 12
x = 3
4 + 3(10 - 23)
4 + 3 × (-13)
4 - 39
-35 << answer
hope this helps, God bless!
