Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
Answer:
Mechanical advantage = Effort distance/Resistance distance
Effort distance = D - Fulcrum = 0.5 m
Resistance distance = A - Fulcrum = 2.0 m
Then,
Mechanical advantage = 0.5/2 = 0.25
Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.
Answer:
x=-6
Step-by-step explanation:
2x+y=-4
5x+3y=-6
solve :
multiply first equation by 3
6x+3y=-12
5x+3y=-6
subtract the two equations : 6x+3y-5x-3y=-12-(-6)
x=-12+6
x=-6
