Answer:
5. TS ≅ ML
6. ∠N≅∠U
9. m∠P = 80°
10. QR = 3
Step-by-step explanation:
The congruent symbol ≅ indicates that the two shapes have the same angle and side lengths.
5. TS are the third and second letter in RSTUV. The third and second letters in KLMNO are ML. TS ≅ ML
6. N is the fourth letter in KLMNO. The fourth letter is RSTUV is U. ∠N≅∠U
9. ∠P is congruent to ∠W. Notice they are both on the longer side and the wider angle. Since m∠P ≅ m∠W, and m∠W = 80°, then m∠P = 80°
10. QR is congruent to XY. They are both the shortest sides of the shape. QR ≅ XY and XY = 3, then QR = 3
Answer:
-38
Step-by-step explanation:
2. Angle Addition Postulate as they are adding both angles
3. 60 + 40 = m <ABC because it's a substitution
4. 100 = m <ABC as it is simplified already
5. Definition of obtuse angle
