Answer:
Step-by-step explanation:
To find the y-intercept of a graph, we can simply set the value of 'x' equal to 0. If we substitute this into the equation y= x²+3/10, we get:
y= 0²+3/10
y=3/10.

Quick vocab:
sin=sine
cos=cosine
tan=tangent
theta=the angle
o=opposite side from angle
h=hypotenuse of triangle
a=adjacent side to angle
Three equations:
sin(theta)= o / h
cos(theta)= a / h
tan(theta)= o / a
Explanation of problem:
sin(x)= o / h
sin(x)= 16cm / 28cm
You'll substitute the 16cm in for o and 28cm for h
This is because 16cm is on the side that's opposite from the angle
28cm is on the hypotenuse of the triangle
One way to find the hypotenuse is look where the 90° is at and it's opposite from that
since you're trying to find the angle you'll have to inverse the sin to get it on the other side of the equal sign
Inverse is doing the opposite of so the inverse of sin is sin^-1
x = sin^-1 (16cm/28cm)
Answer:
x = 34.84990458°
I don't know how far rounded you'll need it
I hope this helped!

angles formed by these tosses are and
degrees to the nearest hundredth.
<u>Step-by-step explanation:</u>
Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.
The Law of Cosines (also called the Cosine Rule) says:
Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
⇒
⇒
⇒
⇒
⇒
⇒
⇒
The Law of Sines (or Sine Rule) is very useful for solving triangles:
We can now find another angle using the sine rule:
⇒
⇒
⇒
So, the third angle =
Therefore, angles formed by these tosses are and
degrees to the nearest hundredth.
