Answer:
The answer is C: 35°
Step-by-step explanation:
The sum of all angles in a triangle is 180°
So, 180°-(60°+85°)
= 180°-145°
= 35°
m∠L = 35°

Answer: 1 is d 2 is a
Step-by-step explanation: ...
Call the midpoint M. Then it must satisfy
... M = (R + S)/2
... 2M = R + S . . . . multiply the above equation by 2
... R = 2M -S . . . . . subtract S
Since we need to use this equation several times, it is convenient to calculate ...
... 2M = 2(6, -10) = (12, -20)
All we need to do is subtract the given value of S from this.
10. R = (12 -0, -20 -8) = (12, -28)
11. R = (12 -9, -20 -(-3)) = (3, -17)
12. R = (12 -(-2), -20 -(-7)) = (14, -13)
Answer:
B) ∠B ≅ ∠K
Step-by-step explanation:
The Angle-Angle-Side Postulate (AAS) states that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.
Given that ∠A ≅ ∠J and AC ≅ JL, then we need that ∠B ≅ ∠K to satisfy postulate AAS (the two angles are ∠A and ∠B in one triangle and ∠K and ∠J in the other one, and the non-included side is AC in one triangle and JL in the other one).
