Tan=y/x and cos=x/r and sin=y/r
If y/x=12/5, then y=12.
If x/r=-5/3, then x=-5
Therefore, sin theta would equal 12/3
<h3>Yes the triangles are congruent by ASA axiom or congruency .</h3>
Because one side of triangle is equal and two angles are equal . So option 1 is your answer .
Try solving for the variable and get everything to one side
Answer:
158.7°
Step-by-step explanation:
Data:
r = 13 in
s = 3 ft
Calculations:
(a) Convert feet to inches
s = 3 ft × (12 in/1 ft) = 36 in
(b) Calculate the angle
Let θ = the angle subtended by the arc.
s = rθ
θ = s/r = 36/13 ≈ 2.7692 rad
Convert radians to degrees
2.7692 rad × (360°/2π rad) = 158.7°
The wheel travels through an arc of 158.7°.
