Answer:
n = 5
Step-by-step explanation:
Given
3( n - 2) = 9 ( 6 - n)
3n - 6 = 54 - 9n
3 n + 9n = 54 + 6
12n = 60
n = 60/ 12
n = 5
Since both triangles have a right-angle, and the two angles at vertex C are also twins, thus both triangles are similar by AA, therefore,
Answer:
x is 55 degrees because the whole angle is a total of 180 degrees. All you have to do is do 180 minus the given angle, 125
Answer:
x = 3
Step-by-step explanation:
5(x-1)+3=13
Distribute the 5
(5x - 5) + 3 = 13
5x - 5 + 3 = 13
x = 3
