Answer:
The only answer is 67 degrees
Step-by-step explanation:
A straight line is 180 degrees and x is one part and the other part is 113 degrees, so if you do 180-113 it will be 67.
Answer:
sin A = 12/13
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite side/ hypotenuse
sin A = 12/13
a= 1+2b, b=1-6, c=2/3d. Hope this helps, I used D as a number in C you don't have to use d.
