As they are vertical angles, their magnitude would be equal.
x = 3x - 60
3x - x = 60
2x = 60
x= 30
In short, Your Answer would be 30
Hope this helps!
Answer : 15 seconds
25% is equal to 1/4, so you can just divide 60 seconds by 4, and that gives you the answer.
Answer:
n = 6 3/7 or 45/7
Step-by-step explanation:
cross-multiply
7n = 45
n = 45/7 or 6 3/7
Answer:
B
Step-by-step explanation:
The triangle UVW is similar (or congruent) to the triangle XZY.
U angle of the triangle UVW = 36 degrees
X angle = 180 - 72 - 72 = 36 degrees
Therefore:
V angle = Z angle = 72 degrees
W angle = Y angle = 72 degrees
Triangle UVW is a isosceles triangle at angle U.
=> UV = UW = 5.7 cm
=> the perimeter of triangle UVW = the perimeter of triangle XZY = 5.7 x 2 + 3.7 = 15.1 cm
