An equilateral triangles has 3 equal sides and 3 equal angles.
All the angles of an equilateral triangle have a measure of 60 degrees.
Using the Pythagorean theorem, the length of the hypotenuse squared is the length of one leg squared plus the length of another leg squared.
Here's the equation for the Pythagorean theorem.
Let c be the length of the hypotenuse.
Let a and b be the length of the two legs.
a^2 + b^2 = c^2
Have an awesome day! :)
Answer:
C
Step-by-step explanation:
According to SohCahToa, cosine is adjacent over the hypotenuse.
The adjacent when looking from angle b, is 21.
The hypotenuse of this triangle is 29.
So Cos B=21/29
Hello There!
2² - 6 = -2
3² - 6 = 3
4² - 6 = 10
Etc....the list goes on
Hope This Helps You!
Good Luck :)

T⁻¹ is the inverse function of T.
To get the inverse function, replace x with y and y with x.
So T<span>⁻¹(x, y): (x + 2, y - 7)</span>
Answer:
x= -59
Step-by-step explanation:
x-31=-90
Adding 31 to both sides we get
x-31+31=-90+31
x=-59
