Answer:
d> -3/16
Step-by-step explanation:
There a absolute value so mark out the negative and 25 / by 16 is 1 so 1 is your answer if you really do the problem on paper
The triangle sum theorem says all 3 interior angles must equal 180 degrees.
so, 43 + 35 = 78. [ 180 - 78 = 102 degrees for the missing angles shared by the 2 triangles.
102 + 18 = 120. [180 - 120 = 60}
leaving the measure of Angle A as 60 degrees.
