In triangle abc, a is a right angle, and ab = 16√3, and the measure of b=30 degrees. What is the length of ac.

salantis [7]

Answer:

the length of ac is 16.

Step-by-step explanation:

Given;

A is right angle, = 90⁰

B is 30⁰

ab = 16√3

↓

↑

A → ← B

If this right angle triangle is considered, length bc is the hypotenuse and length ac is the opposite side of angle B.

The length of ac is calculated as follows;

$tan \ B = \frac{opposite \ side}{adjacent \ side} \\\\tan \ B = \frac{ac}{ab} \\\\ac = ab \ \times \ tan \ B\\\\ac = 16\sqrt{3} \ \times \frac{\sqrt{3} }{3} \\\\ac = \frac{16 \sqrt{9} }{3} \\\\ac = \frac{16 \times 3}{3} \\\\ac = 16$

Therefore, the length of ac is 16.

Find the x-coordinate where the graph of the function f(x) = e(–sinx) has a slope of 0

balandron [24]

$y = e^{-sin(x)}$

$y' = -e^{-sin(x)}(cos(x))$

$0 = -e^{-sin(x)}(cos(x))$

When is cos (x) = 0? at 90° (aka π/2)

Answer: $\frac{\pi}{2}$

What is the best approximation for the perimeter of a semicircle with a dimeter of 12cm?

taurus [48]

Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer when using 3.14 for pi Woops: forgot to add the diameter of 12 so we would have 30.84

A __________________________of a set is those element within the universal set but not included in that set.

shepuryov [24]

Answer:

complement

Step-by-step explanation:

The complement of a set is the set in the universal set that is not included in that set

The universal set contains all elements

For example

U = { 1, 2, 3, 4, 5, 6, }

A = {1, 3, 6}

(complement of A) A' = {2, 4, 5}
