Answer:
a=17√2
Step-by-step explanation:
Hi there!
We are given a right triangle with the measure of one angle being 45°, and one of the sides being measured 17
we need to find a
first, let's find the measure of the other angle
because it's a right triangle, the sum of the acute angles are complementary, meaning they add up to 90°
let's make the unknown degree of the other angle x
so that means to find x:
45+x=90
subtract 45 from both sides
x=45°
that means the measure of the other angle is 45°
You may notice since we have two angles with the same measure, that means this triangle is isosceles.
That means the other leg (the other side that isn't marked) is also 17
of course, you could solve for a using Pythagorean theorem, but there's actually a shortcut:
in 45°-45°-90°Δ, the legs are a specific value, and the hypotenuse (the side opposite from the 90° is the value of the legs*√2 (for example, if the legs are 3, then the hypotenuse is 3√2). To remember the rule, if the legs have a measure of s, the hypotenuse has a measure of s√2
therefore the measure of a is 17√2
Hope this helps!

10. Geraldo Castro rented a car for 4 days at $45 per day, and drove the
car 600 miles at $0.22 per mile. He spent $30 for gasoline and purchased
a collision waiver for $12 per day. What is the total cost for renting the car?
(Section 9-7) *
A. $452
O B. $390
C. $45
O D. $30
Answers
Explanation:
$45 per day= $180
600 miles= 132 ($0.22x600)
Daily collision waiver=$48
As of now the cost is $360 + the $30 of gas= $390.

Answer: 11 goes in the blank in the denominator
The probability as a fraction is 5/11
============================================================
Explanation:
There are 250 red and 300 blue. This gives 250+300 = 550 total marbles.
Divide the number of red (250) over the number total (550) to get the fraction 250/550. Reduce this fraction by dividing both parts by 50. Note how 50 is the GCF of 250 and 550.
Let A = 250 and B = 550.
A/GCF = 250/GCF = 250/50 = 5 which is the numerator already written for usB/GCF = 550/50 = 11 will go in the blank in the denominatorThe fraction A/B = 250/550 fully reduces to 5/11.
We can think of it like saying "There are 5 red marbles out of 11 total".
5/11 = 0.4545 = 45.45% approximately
Eighteen students passed the Science Test. If 18 students is 72% of the total number of students in the class, how many students are in the class?
Answers
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let the total number of students in the class= x
No. of students who passed the test = 18 = 72% of x = 72x/100
Therefore, 72x/100=18
=72x=18*100=1800
=x=1800/72= 25 students.
Hence, total number of students in the class= 25 students

Answers
Answer:
C
Step-by-step explanation:
Sine equals opposite over hypotenuse, which would be y/19. To find y multiply by 19 to get y=19sin33°
The values given are 19 (hypotenuse), y (adjacent side), and the angle (33°)
The formula for cosine is adjacent side divided by the hypotenuse
After plugging in the values given into the formula cosx=ad/h, we have:
Cos33°=y/19 Here, we need to isolate the Y
And, the final result is
19Cos33°= Y
So, the correct answer is the letter D
