Question

Which of the following is a true statement about the angles in the figure below?
A. The m∠3 is 142°.
B. The m∠1 is 99°.
C. The m∠2 is 137°.
D. The m∠4 is 137°.

Answer 1

Answer:

only d is correct

Step-by-step explanation:

angle 4 = angle 1 + 56 degrees , we are given with the measure of 2 angles of a triangle 56 and 43degrees and we need to first find out angle 1 so ( by angle sum property) 43 + 56 + angle 1 = 180 degrees so we get value of angle 1 as 81 degrees so angle 4 equal to 81+56 = 137 degrees, angle 2=43+56 =99 degrees,angle 3 = 43+81=124 degrees
