Measure E is equal to?

Gennadij [26K]

Answer:

114

Step-by-step explanation:

Since DE and EF are equal, DEF is an isosceles triangles.

In isosceles triangle, two angles are equal.

So,

∠F = ∠D = 33

Sum of interior angles in a triangles is 180,

∠D + ∠F + ∠E = 180

33 + 33 + ∠E = 180

∠E = 180 - 33 - 33

∠E = 114

How can a translation and a reflection be used to map ΔHJK to ΔLMN? Translate K to N and reflect across the line containing HJ.

Svet_ta [14]

Answer:

<u>Translate K to N and reflect across the line containing JK. </u>

Step-by-step explanation:

The rest of the question is the attached figure.

From the figure, we can deduce the following:

∠K = ∠N

JK = MN

HK = LN

So, N will be the image of K

By translating K to N, The segment JK will over-lap the segment MN,

Then, we need to reflect the point H across the the line containing JK to get the point L

So, the translation and a reflection that will be used to map ΔHJK to ΔLMN:

<u>Translate K to N and reflect across the line containing JK. </u>
