Step-by-step explanation:
I think it will be right 17.3
Sin of an angle = opposite side / hypotenuse
sin(30) = square root of (x/2) / 4x
1/2 = square root of (x/2) / 4x
1/2 = square root of ((x/2)/16x^2)
1/2 = square root of (1/32x) / ^2
1/4 = 1/32x / *32x
8x = 1
x = 1/8
After u plug in t for everything the answer will be 260.2087
Let x = hours taken by William to assemble a computer.
Let y = hours taken by Douglas to assemble a computer
Because William takes 2 hours less than Douglas to assemble a computer, therefore
x = y - 2
When working together, they assemble 25 computers in 60 hours. Therefore
(x + y hours/computer)*(25 computers) = (60 hours)
25(x + y) = 60
x + y = 2.4
Because x = y - 2, obtain
y - 2 + y = 2.4
2y = 4.4
y = 2.2
x = y - 2 = 2.2 - 2 = 0.2
William takes 0.2 hours (12 minutes) to assemble a computer.
Douglas takes 2.2 hours (or 2 hours, 12 minutes) to assemble a computer.
Answer: 2.2
Answer:
first write the formula
Step-by-step explanation:
Hypotenuse^2 = Perpendicular ^2 + Base^2
only applicable for a right triangle (one of the sides is of measure 90 degree
Give an example
let is assume in Triangle ABC, angle B = 90 degrees
AB = 3cm
BC = 4 cm
to find AC or hypotenuse
Solution
by using pythagoras formula we get
(AB)^2 + (BC)^2 = (AC)^2
(3)^2 + (4)^2 = (AC) ^2
9 + 16 = (AC)^2
25 = (AC)^2
Root of 25 = AC
5cm =AC
Write about how pythagoras theorem was formed
mathematician who derived it
in which year
Application of Pythagorean theorem
Pythagorean Triplets etc.
I think this willbe enough for an essay
GOOD LUCK FOR THE FUTURE! :)
