A triangle has two sides measuring 16 and 21. The included angle is 116°. What is the length of the side opposite the 116° angle

lutik1710 [3]

Answer:

$h =26.4$

C is correct Option

Step-by-step explanation:

Let,

Base of the triangle = b = 16

Perpendicular of the triangle = p = 21

Hypotenuse of the triangle= h = ?

According to Pythagoras theorem;

$h^{2} = b^{2} +p^{2}$

$h^{2} = 21^{2} +16^{2}$

$h^{2} =441+256$

$h^{2} =697$

$h =\sqrt{697}$

$h =26.4$

From complete sets of playing cards (32 cards) we pulled out one card.

AVprozaik [17]

The probability of pulling an ace is 4 out of 32 or 4/32. There are four aces in a complete set of playing cards. If you need me to simplify, it would be 1 out of 8, or 1/8. I hope this is helpful!
