Answer:
I thank its b not sure sorry if its wrong
Answer:
option 2
Step-by-step explanation:
By repeatedly subtracting 360° from the given angle.
1155° - 360° = 795°
795° - 360° = 435°
435° - 360° = 75° ← coterminal angle
Answer:
the answer is (x,y) (1,2)
The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are
and 
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.


So x = 13°. The angles are

The angles of the triangle are 39°, 51°, and 90°.
