Answer:
43˚
Step-by-step explanation:
If angle 5 is 134˚, then that means angle 2 must be 46.
Inside the triangle, we have three angles. A right angle of 90˚, angle 2 of 46˚ and the unknown angle 1. Since the total sum of the angles in a triangle must be 180, we can solve for angle 1:
180 = 90 + 46 + x
Therefore:
x = 43˚
Angle 1 is 43 degrees.
Hope this helps!
