1 answer:
Answer:
A.
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
sin 30°
<u>Step 2: Solve</u>
Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.
Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.
Substituting it into sin, we have:
sin 30° = 1/2 = 0.5
∴ our answer is A.

Answer:
<h2>NONE OF THEM</h2>Step-by-step explanation:
From the graph,
y and x intercepts are and approximately
respectively
for A, C and D :
x intercept the value of y=0, and y intercept x=0.
x and y intercepts are and approximately
respectively
for B:
x and y intercepts are and approximately
respectively
Therefore x and y intercepts for the lines and
they are not equal to the x and y intercepts of the given graph
