Consider the triangle. Right triangle A B C. Side A C is 24 centimeters, C B is 10 centimeters, and hypotenuse A B is c. Find th
natita [175]

Answer: The length of the hypotenuse is 26 cm

Step-by-step explanation: Please refer to the attached diagram

The triangle ABC is drawn as described such that the right angle is at point C and line AB is the hypotenuse which is yet unknown.

Since we have a right angled triangle with two sides known and one unknown, we can apply the Pythagoras theorem which states that

AC² = AB² + BC² where AC is the hypotenuse and AB and BC are the other two sides

In this question the hypotenuse is AB, so we now have;

AB² = AC² + CB²

AB² 24² + 10²

AB² = 576 + 100

AB² = 676

Add the square root sign to both sides of the equation

√AB² = √676

AB = 26

Therefore the length of the hypotenuse is 26 cm

What is the value of  sinθ, given that cosθ=−2/5 and  sinθ>0? Simplify radicals and rationalize the denominator, if necessary
Vadim26 [7]
\cos\theta=-\dfrac25
\sin\theta=\pm\sqrt{1-\cos^2\theta}=\pm\dfrac{\sqrt{21}}5

Take the positive root, since it's given that \sin\theta>0.

\sin\theta=\dfrac{\sqrt{21}}5

A) a shopkeeper buys a camera for $300 and sells it at $360. Calculate the percentage profit.
Lilit [14]
A) profit/original price x100 =percentage profit

(Profit: 360-300=$60)

=60/300 x100
=20%

b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720

Profit without discount: 720-600= $120

120-100= $20 discount

20/720 x100 =2.78%
