Answer:
the horizontal are called x-axis, while the vertical are called y-axis
Z= 90
It’s a circle theorem, drawing a triangle from a diameter of a circle creates a right angle
And then there’s always 180 degrees in a triangle, so
Y= 40
I assume it is the diameter of the outer wheel they are asking for.
connect OD, which is the radius of the wagon to the outer edge of the wheel.
OYD is a right triangle. use the hypotenuse theorem:
OY²+YD²=OD²
7²+24²=OD²
OD=√625
OD=25
the radius is 25, the diameter is then 50.
Note: if it is the diameter of the inner circle they are asking for, I don't know.
Answer:
40%
Step-by-step explanation:
Make it so the denominator is 100 since a percentage is out of a 100.
2/5 x 20/20 = 40/100
Now turn 40/100 into a percent. Should be simple. 40 out of 100 is 40%.
