Hope this helped :)
Answer:
The measure of ∠ C is 180°-3∝
Step-by-step explanation:
We are given a ΔABC
∠A = ∝
∠B = 2∝
Angle sum property of triangle : The sum of all angles of triangle is 180° is called angle sum property of triangle
So, ∠A+∠B+∠C=180°
∝+2∝+∠C=180°
3∝+∠C=180°
∠C=180°-3∝
Hence the measure of ∠ C is 180°-3∝
Answer:
Step-by-step explanation:
3(3)^2 + 5(3) + 25
3*3 = 9, 5*3 = 15
3(9) + 15 + 25
27 + 15 + 25 = 67
Answer:
D. 158.4 km²
Step-by-step explanation:
Area of sector = θ/360 * πr²
Where,
θ = 150°
r = 11 km
Substitute
Area = 150/360 * π * 11²
Area = 158.38863 ≈ 158.4 km² (nearest tenth)
[Add] 1.
-9h = 30 + 15
[Simplify] 2.
-9h = 45
[Divide] 3.
h = - 45/9 ( A negative Divide)
[Answer] 4.
h = -5
