Step-by-step explanation:
Given that, a series of triangle,
For the sine and cosine to be equal, then,
Sinθ = Cosθ
From, trigonometry identities
Sinθ = Cos(90-θ)
Then,
θ = 90-θ
θ + θ = 90
2θ = 90
θ = 90 / 2
θ = 45°
From the triangle given, using trigonometry ratio,
Sinθ = opposite / hypotenuse.
Sinθ = 20 / 25
Sinθ = 0.8
θ = arcsin(0.8)
θ = 53.13°
The other angles at the triangle is
90-53.13 = 36.87°.
Answer:
A (-1,-2), B (-4,0), C (3,3)
Step-by-step explanation:
Answer:
{2x + 1}{ {x}^{2} } \\ = \dfrac{2(5) + 1}{ {5}^{2} } \\ = \{11}{25}
Answer is 11/25.
Step-by-step explanation:
Convert to slope - intercept form:-
-7x + 3y = 15
3y = 7x + 15
y = (7/3)x + 5
Slope = 7/3 and y intercept = 5
