Find the missing angle according to the Triangle Sum Theorem.

x = 60°

Step-by-step explanation:

Triangle Sum Theorem: The sum of interior angles always equals 180°.

We are already given two angles, 30° and 90°. Add these together and subtract it from 180° to get your answer.

x=60

Step-by-step explanation:

Because a triangleś angles need to be summed to 180 degreeś.

90+30+x=180

180-90=90

90-30=60

x=60

.25

step-by-step explanation:

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
