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:
-3/5
Step-by-step explanation:
3/ -5 is also equal to -3/5 or - (3/5)
1 quart = 32 ounces
2 x 32 = 64
$6.40 divided by 64 ounces
.10 per ounce
Answer:
V≈37.7
Step-by-step explanation:
V= πr2h/3 = π·32·4/3 ≈ 37.69911
Answer:
see explanation
Step-by-step explanation:
∠ PQS + ∠SQR = ∠ PQR , substitute values
13x + 4 + 10x - 1 = 141 , that is
23x + 3 = 141 (subtract 3 from both sides )
23x = 138 ( divide both sides by 23 )
x = 6
Thus
∠ PQS = 13x + 4 = 13(6) + 4 = 78 + 4 = 82°
∠ SQR = 10x - 1 = 10(6) - 1 = 60 - 1 = 59°
