Find the missing angle in a triangle with the given sides.

Step-by-step explanation:

Since the shape is a triangle it means that all it's interior angles sum to 180°

To find the missing angle sum up the known angles and subtract them from 180°

That's

X + Y + Z = 180°

89° + 90° + Z = 180°

Z = 180 - 179°

We have the final answer as

Hope this helps you

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
