Angles 1 and 2 are supplementary.
which equation represents the relationship between their
measures?
m21+ m22 = 90°
m21 + m22 = 100°
mz1 + m 22 = 180°
m21+ m 22 = 2009
save and evit

Step-by-step explanation:

m∠1 + m∠2 = 180°

Supplementary means sum of two angles is 180°

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
