Find the indicated side of the triangle

Mathematics
1 answer:
Vadim26 [7]3 years ago
8 0

Answer:

7√2

Step-by-step explanation:

Knowing that the angle is 45° (or π/4 radians) and the opposite leg has a length of 7,  you can find the length of b with:

7 / b = sin(π / 4)

7 / (sin(π / 4)) = b

b = 7 / (1 / √2)

b =7√2

A simpler way to get the answer is to note that a right triangle with one 45° angle must be an isoceles right triangle, so both legs are the same length. Using the Pythagorean Theorem:

a² + 7² = b²

Since we know a = 7,

7² + 7² = b²

b = √(2 * 49)

b = 7√2

A cylinder has a volume of 200in^3. Determine the volume of a cone whose radius and height are equal to that of the cylinder
katrin [286]

Answer:

66.67 in^3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone =  1/3(nr^2h)

n = 22/7

r = radius

the volume of a cone is 1/3 that of a cylinder

volume of the cone = 1/3 x (200) = 66.67 in^3

8. Which of these is not an integer 6 6 A 3 C E 3
Mnenie [13.5K]
An integer is a whole number. 

The answer isn't A, because 6/3=2 and 2 is a whole number.

The answer isn't C, because 6/2=3, and 3 is a whole number.

The answer therefore has to be B, because 3/6=1/2 and 1/2 isn't a whole number or an integer.

Find the x- and y- intercept of the line. x+4y=36 Answer choices are: A. x-intercept is 4; y-intercept is 1/ B. x-intercept is 1
agasfer [191]
It would be D. x-intercept = 36; y-intercept = 9

if you know that the x-intercept is when the line crosses the x-axis and the same way with the y-intercept, all you would need to do is graph it, (or use desmos.com) and find where the points me the x and y axis.
