143°

Step-by-step explanation:

The sum of angles in a triangle should be 180, so ∠1 = 180-53-90 = 37.

∠1 and ∠3 should add up to 180, so ∠3 must be 180-37 = 143.

143

Step-by-step explanation:

if m(1) = 53

in triangle EDF , all angles sum is 180

90 +  53 + m(2) = 180

m(2) = 180-143

= 37

m(2) + m(3) = 180 as it is straight line

m(3) = 180 - 37

= 143

the radius is 2 times the diameter.

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
