Answer:
x=4
,y=8
Step-by-step explanation:
sin∠SRT = sin∠TSV,
SO 
, 
=80,x=
;
In the same way:
sin∠RSV = sin∠RTS,
SO 
，
=320,y=8
<span>the longitude of the ramp is determined by the Hypotenuse, we have the angle(4.5Âş), and the opposite side (3ft), so with the Sin(x) trigonometric function ( sin(x)=opposite/hypotenuse ) we can calculate the answer.
Using the formula, hypotenuse=opposite/sin(x)
Hypotenuse=3ft/sin(4.5)
hypotenuse=3ft/0.0784591
hypotenuse=38.236482
the ramp must be 38.2 ft long.
the calc must be in degrees to get an accurate answer to any trigonometric function</span>
Answer:
a) x = 5
b) x = 12
Step-by-step explanation:
x + 3 = 8
Subtract 3 on both sides.
x = 8 - 3
x = 5
x - 5 = 7
Add 5 on both sides.
x = 7 + 5
x = 12
Answer
The first one is equal and the second one is the first choice.
