This is a right triangle (hence the 90° angle), so you'd find the legs (both are the same length of a right triangle) by using Pythagoras Theorem (a2 + b2 = c2) Since you have the hypotenuse (6"), just go backwards. 62 = 36 = a2 + b2. Like I said before the legs are the same length so you can rewrite it as 36 = 2x2, where x = either a or b. Then just solve for x.
Answer:
b .
x = 3
y = 3
Step-by-step explanation:
Using the pythagorean identities for 30-60-90° triangle,
we know the ratio of the sides is x - x√3 - 2x
Since 2x = 6
Then smallest side is x (opposite ∠30°) = 6/2 = 3
The other side y , opposite ∠60° will be x√3 or 3√3.
P: -1/2
q: 1
r: 7/2
These are the slopes because the slope is the coefficient in front of x. On top of that you need to get y by it's self and have only one y.
Answer:
The answer is G
Step-by-step explanation:
S=80.5km/h
D644
T8 hours
3x - 3 = x + 5
2x -3 = 5
2x = 8
x = 4
you can plug 4 into each one to determine that they both equal 9 and that entire length is equal to 18
