Step-by-step explanation:
We require to find the third side of the triangle.
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x represent the third side, then
x² + 15² = 17², that is
x² + 225 = 289 ( subtract 225 from both sides )
x² = 64 ( take the square root of both sides )
x = 
= 8
Thus
tanΘ = 
= 
cosΘ = 
= 
sinΘ = 
= 
cscΘ = 
=

40÷5= 8 You have to see how many time 5 can go into 40
1. see how many times 5 goes into 4 none so the first number is 0
2. then you see how many time 5 can go into 0 o times
3. so you have to see how many time you can count 5 into 40
(count by 5's) 5,10,15,20,25,30,35,40 that should be 8 times total!
a^4+2a+8 because if you combine like terms that is what you get
Answer:
Step-by-step explanation:
The midpoint between two points is just the average of the coordinates.
mp=((x2+x1)/2, (y2+y1)/2)
mp=((-6-2)/2, (-8-6)/2)
mp=(-4, -7)
Answer:
So, lets go to the first posible number that ends in 8 and is multiple of 8 and greater than 16. This is 48. 48 = 6*8, this is, lets think about 6 correct answers that sum 48 points.
We now need to subtract a number to 48 that gives us 13. Which is?
48 - x = 13 <----> x = 35
So, we need a number of incorrect answers that sum 35. As every wrong answer sums 5 points, we need 7 wring answers (7*5 = 35):
8*6 - 5*7 = 48 - 35 = 13 points!!
