Answer:
Sin 90°=1
Step-by-step explanation:
A unit circle is a circle with a radius of 1 .Because the radius is 1, it is possible to directly measure the sine, cosine and tangent.
<em>using the unit circle where 90° is the limit as the hypotenuse approaches the vertical y-axis which is positive.</em>
Sine=opposite/hypotenuse
Sin=O/H
<u>Applying the limits</u>
Sine 90°=1/1= 1
cos 90° =0/1 =0
or
When the angle formed at the origin of the unit circle in the 1st quadrant is 0°, cos 0°=1 sin0°=0 and tan 0°=0
When we increase the angle until it is 90°, cos 90°=0, sin 90°=1 and tan 90°=undefined
a. The equation computed shows that the number of paid vacation days has she earned will be 17 days.
b. The time when she will reach the maximum number of paid vacation days allowed is 6 years.
<h3>How to compute the equation?</h3>
a. The equation computed shows that the number of paid vacation days has she earned will be:
= 2 + 3x
x = 5
= 2 + 3(5)
= 2 + 15
= 17 days.
b. The maximum number of days for a pod vacation will be:
= 4 × 5
= 20 days.
The time when she will reach the maximum number of paid vacation days allowed will be:
20 = 3x + 2
3x = 20 - 2.
3x = 18
x = 18/3
x = 6 years

That's Intersecting Secants, and we get
EC × ED = EB × EA
(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 9x + 20 = x^2 + 13x + 12
8 = 4 x
x = 2
Check: 3(14)=42 6(7)=42 good
Answer: 2
Ok, here we go.
The x-value is given(Great!), so now we need to find y-value for slope
The average slope, according to the calculator, is 0.627
4 the answer is 180 degrees as the sum of all sides of a triangle = 180degrees
