Please help I am confused will give Not sure how to find the measurements of 2, 3 and 4

Traversals, Eh?

2-99 degrees

3-81 degrees

4-81 degrees

Step-by-step explanation:

So to find the measures of these angles, we need to find the relationship between these angles.

1 and 2 are Alternate Exterior angles(Maybe, been a while since I have done traversals).

They are supplementary angles the sum of their measurements is 180

180=<1+<2

So, I'll spare the math and let you figure out how I got it.

<2=99 degrees

1 and 3 are vertical angles, meaning they have got the same angle measure.

So, <3 is 81 degrees

1 and 4 are Corresponding Angles, meaning they have the same angle measure.

So, <4 is 81 degrees

Hope This helps!

P.S. Google the Names of the angles, I might be wrong!

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.

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465
