<span>F the hypotenuse of a 45°-45°-90° triangle is 13.
We can see that this is an isosceles triangle,
and its two legs are equal.
From Pythagorean theorem we can write
(leg)² + (leg)² = (hypotenuse)²
2</span>(leg)²= (hypotenuse)²
2(leg)²= 13²
(leg)² = 13²/2, we need only positive root,
leg = √(13²/2)=13/√2=(13√2)/2 exact value
leg ≈ 9.19 approximate value
Answer:
I think it is A
Step-by-step explanation:
the reason i am saying A is that you don't really know how many guests are coming it could be 10 or 15 or even more.
Answer:
21, 42, 63, 84.
Step-by-step explanation:
The cards with a star and a circle must be multiples of 3 and 7.
So these must also be multiples of 21:
These are 21, 42, 63 and 84.
The total distance that will be covered is
25 - 3 = 22
If we let x be the head start that Ario will have before Miguel starts, then we have the equation
x / (22 - x ) = 1/4
Solve for x
x = 4.4
Ario will have to travel 4.4 meters before Miguel starts
