Triangle ABC is an oblique triangle. If angle A equals 57°, angle B equals 73°, and AB equals 24 in, what is the length of AC?

natulia [17]

Step-by-step explanation:

$\huge{\underbrace{\overbrace{\mathfrak{\pink{Answer:}}}}}$

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°

And using rhw Law if Sines, we have.....

AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in

How do you write (243)^ 3/5 in radical form? THEN simplified?! *PLEASE HELP

SOVA2 [1]

Answer:

Step-by-step explanation:

If you have an exponent that is a fraction, you need to make a radical with the index from the denominator and an exponent of the radicand from the numerator.

(243)^3/5=( $\sqrt[5]{243}^3$ )

This would come out as $\sqrt[5]{14348907^}$ . this further simplifies down to the final answer of 27

Last season, your

Katarina [22]

Answer:

55%

Step-by-step explanation:

The percent change formula is written like this:

$|\frac{change - original }{original}|$ . In this scenario, the "change" or new value is 31, because it is this season, and the original is last season. Now, 31-20 = 11, and 11/20 = 55%.

A triangle has sides with length of 12 miles 16 miles 20 miles Is it a right triangle

svetlana [45]

Answer:

Yes! This is a right triangle.

Step-by-step explanation:

To solve this problem, you need to use the Pythagorean Theorem, which is: $a^2+b^2=c^2$ . In this equation, "A" represents the smallest length, "B" represents the next smallest length, and "C" represents the largest length. If a triangle is a right triangle, then the A squared + B squared equals C squared.
