Answer:
2+18
Step-by-step explanation:5+123
Step-by-step explanation:
Distance Chase thought he travelled = 40 feet
The actual distance travelled by him = 32 feet
Error % = (40 - 32)/ 100
= 8/100
= 0.08
Recall that to calculate the distance between two points (a,b) and (c,d) we use the formula
![\sqrt[]{(c-a)^2+(d-b)^2}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%28c-a%29%5E2%2B%28d-b%29%5E2%7D)
In our case we have a=-2, b=5, c=4 and d=5. So we get
![\sqrt[]{(4-(-2))^2+(5-5)^2}=\sqrt[]{6^2}=6](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B%284-%28-2%29%29%5E2%2B%285-5%29%5E2%7D%3D%5Csqrt%5B%5D%7B6%5E2%7D%3D6)
So the distance between both points is 6
That’s an acute triangle since all angles seem less then 90 degrees
Answer:
90
Step-by-step explanation:
Given: Measure of one side of equilateral triangle = 
Measure of another side of equilateral triangle = 
In equilateral triangle all three sides are equal in length.Therefore,




On substituting the value of x in side of equilateral triangle,
One side of equilateral triangle = 
Perimeter of equilateral triangle = 3 ( length of one side) ........( given)
perimeter of equilateral triangle =
