*WILL GIVE BRAINLIEST FOR BEST ANSWER* ∠3​ and​ ∠4​ ​are complementary angles. m∠4 = 49°

What is the measure of ​​∠3​?

Question 3 options:

A. 131

B. 41

C. 139

D. 49

B. 41

Step-by-step explanation:

Complementary angles mean when the sum of two angles = 90° In this situation, Angle 3 and Angle 4 add to give us 90°.

So all we have to do is 90 - 49 to give us Angle 3.

90 - 49 = 41°

Therefore the answer is B. 41

I hope this helps you!! ^-^

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
