Question

Given Trapezoid JOKE with m

Answer 1

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 2

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°
