Answer:
-2k^2+3k-2
Step-by-step explanation:
(4k^2– 12) – (6k^2– 3k – 10)
Expanding using distributive prop.
4k^2-12-6k^2+3k+10
-2k^2+3k-2
Answer:
We square the 2 smallest sides and sum them:
27^2 = 729 + 36^2 = 1,296
729 + 1,296 = 2,025
This equals the longest side squared 45^2 = 2,025
When this occurs the triangle is a right triangle.
Step-by-step explanation:
Choice given:
<span>33.6°
39.8°
50.2°
56.4°
I drew the figure.
I got 12 ft as the hypotenuse, 10 ft as the opposite.
Sin</span>Θ = opposite / hypotenuse
SinΘ = 10/12
SinΘ = 0.83
I used the calculator to get the value of each angle using the sine function
sin(33.6°) = 0.55
sin(39.8°) = 0.64
sin(50.2°) = 0.77
sin(56.4°) = 0.83
The angle where the wire meets the ground is approximately 56.4°
Answer:
Step-by-step explanation:
Considering triangle CNR and triangle WNO, there are:
∠C = W
CN = WN
∠CNR = ∠WNO (2 opposite angles)
deduce triangle CNR = triangle WNO
deduce RN = ON
