Question

HELP!!! PLEASE!!!!
Elise is measuring the angles of a triangle. She measures the first two and gets 30° and 100°. What should be the measure of the third angle?

Answer 1

Answer:

50 degrees.

Step-by-step explanation:

The angles of a triangle will always add up to be 180, so add and subtract to find the missing value. :)

Answer 2

Step-by-step explanation:

a triangle is 180 degree

so: 180-100 is 80 degress

80-30 is 50 degress

therefore angle 3 is 50 degrees
