Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
Answer:
-18
Step-by-step explanation:
*2, *(-2), *2, *(-2) ...
Answer:
1. y = (3x^2 - 4)
2. y = (-x^2) + 2
3. y = (-x^2 - 8)
4. y = (3x^2 - 2) + 4
5. y = (3x^2 + 4)
6. y = (-1/4x^2)
