<h2>Answer:</h2>
55°
<h2> Step-by-step explanation:</h2>To solve this, follow these steps:
i. <em>Make a sketch of the problem</em>.
The sketch has been attached to this response.
ii. <em>Label the sketch properly</em>
As shown in the sketch, θ is the angle between the x-axis and the terminal side resulting from connecting the origin to (5,7).
iii. <em>Solve using the tangent trigonometric ratio</em>
With the proper sketch and labelling, a right triangle is formed with the adjacent and opposite sides to the angle being 5 units and 7 units respectively.
Using the tangent formula,
tan θ = opposite / adjacent
tan θ = 7 / 5
θ = tan⁻¹ (7/5)
θ = tan⁻¹ (1.4)
θ = 54.46
θ = 55° to the nearest integer.
Therefore, the angle made by the x axis and the terminal side resulting from connecting the origin to (5,7), rounded to the nearest integer is 55°
Answer:
csc (- 30)° = - 2
Step-by-step explanation:
Using the trigonometric relationship
csc x = and the exact value sin30° =
sin(- 30)° = - sin30° = - , thus
csc (- 30)° = = - 2
Answer:
See explanation
Step-by-step explanation:
The standard compound interest formula is where:
P is the principal amount
r is the interest rate (typically as a percentage)
t is the time
n is the times compounded per unit of time
