14. B (4, -2)
15. I am not exactly sure about this one but I would say either A or B.
Answer:
the missing side lenght = x
0 < x < 15+10
0 < x < 25 cm
Answer:
a = 33 degrees, b = 147 degrees
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees, and to solve for the angle on the other side of 109 degrees is 71 degrees, so to solve for a, have 180 minus 71 and 76. Then the sum of 71 and 76 is angle b since its the result of a subtracting from 180.
