MZDAC = 20° and m ZCAB = 40°.
What is the degree measure of ZDAB?

I believe the answer is 60 degrees

Step-by-step explanation:

You're basically adding both 20 and 40 degrees since it's asking the measures of both which is 60 hopefully I'm correct

i need a picture

step-by-step explanation:

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.
