Answer:
<h2>
90°</h2>
Option D is the correct option
Step-by-step explanation:
As RT is a tangent on point P, so it will form a right angle at point P with the radius.
So, angle APT = 90 degrees.
Hope this helps...
Good luck on your assignment...
Answer:
B
Step-by-step explanation:
We want to determine an equivalent trignometric identity with the given expression:
We can factor out a cos(x):
Recall from the Pythagorean Identity that:
Therefore:
Substitute:
Our answer is B.
All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Given that:
Sine function
being
Cosine function
being
We will demonstrate the identity above. First of all, we need to square each equation, so:
Adding these two equations:
But as shown in the figure, using Pythagorean theorem
is always equal to 1, then:
The relation to right triangles is that:
<span>The hypotenuse is always equal to 1
</span>The opposite side is equal to
The adjacent side is equal to
Answer:
.35078
Step-by-step explanation:
2x^2+5x-2=0
x = - b + √b^2 - 4 ac / 2a
x = - 5 + √25 - 4(2)(-2) / 2(2)
x = - 5 + √41 / 4
= 0.35078
11x + y = -11
subtract 11x from both sides
y = -11x - 11
