In the figure, Ð1 and Ð3 are vertical angles, and Ð2 and Ð4 are vertical angles.
Ede4ka [16]

Answer:

mÐ4 = 30°

Step-by-step explanation:

Vertical angles are angles that are opposite to each other, thus are said to be equal.

Since,

i. Ð1 and Ð3 are vertical angles

ii. Ð2 and Ð4 are vertical angles

This implies that the measure of Ð1 and Ð3 are congruent. And also the measure of Ð2 and Ð4 are congruent.

So that, if mÐ2 = 30°, it would be expected that mÐ4 has the same measure. This implies that mÐ4 = 30°.

Pleasee help me with this anyone..
vlabodo [156]

Answer:

Step-by-step explanation:

You need to set up a proportion

Let x = NK

7/13 = x/56    Notice that the longest side of the small trapezoid is the denominator of the fraction  on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.

Cross multiply

13x = 7*56                Combine the right

13x = 392                 Divide by 13

x = 392/13

x = 30.15

NK = 30.15
