its odd you're in high school and you're asking this but its 9
Answer:
B
Step-by-step explanation:
Cos is the adjacent side over the hypotenuse. The adjacent side to <E is side ED. The hypotenuse is side EF. ED/EF. They do not go right out and give you this choice, but you see that B says the same thing.
Answer:
80 games
Step-by-step explanation:
10wins/16 games=50 wins/? games
10 times 5=50 so 16 times 5 =80
10.g=16.50
10/g=800/10
g=80 games
Answer:



Step-by-step explanation:
<h3>QUESTION-2:</h3>
we are given a right angle triangle
it's a 30-60-90 triangle of which FH is the shortest side
remember that,in case of 30-60-90 triangle the the longest side is twice as much as the shortest side thus
our equation is

divide both sides by 2


<h3>Question-1:</h3>
in order to figure out GH we can use Trigonometry because the given triangle is a right angle triangle
as we want to figure out GH we'll use sin function
remember that,

let our opp, hypo and
be GH, 4√10 and 60° respectively
thus substitute:

recall unit circle:

cross multiplication:

simplify multiplication:

divide both sides by 2:

<h3>QUESTION-3:</h3>
Recall that, the sum of the interior angles of a triangle is 180°
therefore,

simplify addition:

cancel 150° from both sides
