Answer: N=6
Step-by-step explanation:
Add 34 degrees with the 90 degree angle and you get 124
Then add 124 to your other equation (9n +2)
Make that equation equal to your straight angle 180 and solve.
9n + 126 = 180
9n = 54
n= 6

(cos^-1)(17/18)
Sorry buddy I forgot the answer
The figure suggests that the two sub-triangle are similar, because they are both right and the angle at the top is the same.
If that is the case, we can claim that the correspondent sides are in proportion:
Solving for x we have
