Answer:
Yes
Step-by-step explanation:
If you are looking for an area of a triangle that is not a right triangle, and it shows the height of that triangle (it should be a dotted straight line), than you can use the formula to get the area.
So if you know the base and height of a non right triangle, you can use the formula.

Step-by-step explanation:
object is 10 m/s. If the force is changed to 90 N, what will be the acceleration of the object?
Answer:
acceleration would be 9 meters per second squared
Step-by-step explanation:
If quantity "A" varies directly with quantity "B", then we can write:
A = kB
Now, this problem says that force (f) varies directly with acceleration (a). So we can write:
f = ka
Given f = 100 and a = 10, so we substitute and find k (the proportionality constant). Shown below:
f = ka
100 = k(10)
k = 100/10
k = 10
So, we have
f = 10a
Now, force is 90, so what's the acceleration?
90 = 10a
a = 90/10
a = 9
So, the acceleration would be 9 meters per second squared
