find the missing measurement

Answer:
34 degrees
Step-by-step explanation:
Every quadrilateral has 4 interior angles with the sum of 360 degrees.
In this case, a right trapezoid, with 2 of its angles already known: 90 & 90
The third angle is given to us: 146
Set up equation:
90 + 90 + 146 + w = 360
326 + w = 360
w = 34 degress
Answer:
34⁰
Step-by-step explanation:
We know that the sum of angles in a quadrilateral is 360⁰
Now,
90⁰+90⁰+w⁰+146⁰=360⁰
w⁰+146⁰=180⁰
w⁰=180⁰-146⁰
w⁰=34⁰
