Triangle ABC is a right triangle, meaning we can use the Pythagorean Theorem to find x.
The formula for the Pythagorean Theorem is:

where a is the hypotenuse, and b and c are the legs.
In this problem, we have the vertical leg as 16, the horizontal leg as x, and the hypotenuse as 20. Therefore, we can say that

Therefore, we can plug into the formula to find x:

We first change the variable c to x and square both sides of the equation. Then we subtract b^2 from both sides.

We square root each side to find the variable answer for x. Then we plug in the numbers:

We find that x = 12. The answer is A. 12.
Answer:
12
Step-by-step explanation:
(3j-h)+3
Plug in numbers:
(3(5)-(6))+3
Solve:
(15-6)+3
9+3=12
Answer: multiply by 3
Step-by-step explanation:
I know this because the relation ship applies to all of the number, for example 3 x 3 = 9 and so on.
Answer
The triangle in the figure 4 is correct .
Reason
by using the trignometric identity

Thus


Now in the figure (1)


on simplify

thus side length measures in the figure (1) is not correct .
Now in the figure (2)

thus side length measures in the figure (2) is not correct .
Now in the figure (3)

thus side length measures in the figure (3) is not correct .
Now in the figure (4)

Therefore the figure (4) is correct triangle has side length measures that could be correct
Hence proved
y=28×9
=252
x=334-150
=184
h=254×100
=25400
Step-by-step explanation:
to check the equations substitute the values by the variables
