Answer:
∠C' = 66°
Step-by-step explanation:
Because triangles ABC and A'B'C' are similar, their angles are still the same; only their side lengths are different, though still proportionate.
Hence, ∠A = ∠A', ∠B = ∠B', and ∠C = ∠C'.
Here, we're given that ∠A = 68, which means ∠A' = 68; we also know that ∠B = 46, so ∠B' = 46.
We want to find C', so remember that all angles in a triangle sum to 180:
∠A' + ∠B' + ∠C' = 180
68 + 46 + ∠C' = 180
114 + ∠C' = 180
∠C' = 66°

Answer:
Step-by-step explanation:
v(x)=12-2x-5
v(-2)=12-2(-2)-5
=11
v(0)=12-2(0)-5
=7
v(5)=12-2(5)-5
=-3
Answer:
2(5) because the irrational swaps the 5

Answer:
Total = 30.75cm squared
Step-by-step explanation:
Area of trapezium = (A+b)h divided by 2 = 15cm squared
area of triangle 1 = 1/2 x b x h = 3 cm squared
Area of triangle 2 = 2.25 cm squared
Area of trapezium at the bottom = 10.5 cm squared
Total = 30.75cm squared
