Answer:
The answer is B (AKA) 102
Step-by-step explanation:
180-78
one angle is 180 degrees
Let x = one of the legs.
Then, the other leg = x + 3.
Ed will use the Pythagorean Theorem to find the hypotenuse.
So, let a = x one leg. Let b= x + 3 the other leg. And, let c = 15 the hypotenuse.
The Pythagorean Theorem is:
c^2 = a^2 + b^2, where a and b are the legs and c is the hypotenuse.
We have:
15^2 = x^2 + (x + 3)^2
225 = x^2 + x^2 + 6x + 9
Rearranging:
2x^2 + 6x - 216 = 0
Divide by 2:
x^2 + 3x - 108 = 0
Solve by factoring:
(x - 9)(x + 12) = 0
So, x = 9 and x = -12. (x = -12 is not a valid answer.)
x = 9
x + 3 = 12
Conclusion: The legs of the right triangle are 9 inches and 12 inches.

Answer:
d. 6.99
Step-by-step explanation:
You have a right triangle with the right angle marked.
The hypotenuse is opposite the right angle and has no length given.
For the 25-deg angle, the side with length 15 is the adjacent leg, and the side with length x is the opposite leg.
The trigonometry ratio that relates the opposite leg to the adjacent leg is the tangent ratio.
Solve for x by multiplying both sides by 15.
Use a calculator to find the value of x.
Answer:
c.2
Step-by-step explanation:
f(x)=2 and where is x you place it with 2 and it won't change because there is no another number is the equation of f(X)
