Question

What's the missing measurement ? pls help :]

Answer 1

Answer:

Step-by-step explanation:

Sum of all angles of a triangle = 180

1) 60 + 87 + b = 180

          147 + b = 180       {Subtract 140 from both sides}

                   b = 180 - 147

b = 33

2) b + 83 + 30 = 180

          b + 113 = 180    {Subtract 113 from both sides}

                  b = 180 - 113

b = 67

first one: 33 degress

second one: 67 degrees

Step-by-step explanation:
