17/25 is a reduce fraction of 51/75
Answer:
x = 25
Angle B = 65 degrees
Angle C = 50 degrees
Step-by-step explanation:
All triangles will add up to 180 degrees.
65 + 3x - 10 + 2x = 180
Combine like terms
55 + 5x = 180
Subtract both sides by 55
5x = 125
Divide both sides by 5
x = 25
Plug in the value for x in angle B:
3(25) - 10
75 - 10
65
Do the same for angle C:
2(25)
50
Check your work:
65 + 65 + 50 = 180
180 = 180
Correct
Answer:
C 3x + 12
Step-by-step explanation:
3(x + 4)
The 3 gets distributed to each term inside the parenthesis
3(x + 4) = 3x + 3*4
3(x + 4) = 3x + 12
