Question

2. Fill in the blank. In the triangle below, z = _____.

Answer 1

z=48 because it is a triangle so it will equal 180. You have 42 and 90 so far and you need a total of 180 so do the math

Answer 2

The measure of angle z is equal to
`z=48\°`

Explanation:

we know that

In the right triangle of the figure

`z+42\°=90\°` -----> by complementary angles

so

solve for z

`z=90\°-42\°=48\°`
