Answer:
multiply the first equation by - 7 to get - 28x - 7y = - 28
Step-by-step explanation:
This then results on adding the 2 equations as
- 24x = 0 ⇒ x = 0 and y = 4
solution to system is (0, 4 )
Since quadrilaterals have interior angles that add up to 360, then subtract the known values from 360
360 - 90 - 90 - 146 = 64
Angle C = 64
Divide the numerator into the denominator to get 0.425
Place them horizontally or vertically
Answer:
14.526 is the answer I think
