Given Trapezoid JOKE with m
2 answers:
Answer:
Step-by-step explanation:
In trapezoid JOKE, JO // EK
m∠J + m∠E = 180 {so-interior angles are supplementary }
m∠J +80 = 180
m∠J = 180 - 80
m∠J = 100
m∠O + m∠K = 180 {Co-interior angles are supplementary}
m∠O + 50 = 180
m∠O = 180 -50
m∠O = 130
Answer:
m∠J =90°
m∠O = 140°
Step-by-step explanation:
We see here angle J having 90°, pure right angle shape.
m<J=90
Then we find the total interior angle using (n-2)*180
(4-2)*180
360°
So, m∠O = 360° - m∠J - m∠E -m∠K
m∠O = 360° - 90° - 80° -50°
m∠O = 140°
