In this problem
You have a triangle with 3 sides labeled A, R, O and 3 vertices labeled J, K, E.
To name a triangle, what you do is simply list all of its vertices.
The order doesn't matter.
So
let's take a look at all the possible choices.
A. EJR - Nope.E and J are OK. But R is the line segment.
B. KE - Nope. K and E is OK, but Only has 2 of the vertices.
C. JE - Nope. J and E is OK, but Only has 2 of the vertices.
D. KEJ - Yes. All three vertices have been named. This is an acceptable name for the triangle.
E. JAOE - Nope. Only has 2 of the vertices and A and O are line segments
F. JKE - Yes. All three vertices have been named. This is an acceptable name for the triangle.
therefore
the answer is
KEJ and JKE
Anything raised to the first power is just that number. For example 5^1=5. So 10^1=10
Density curves go up. So D and E are the best answers.
Split the shape into two shapes
A square
Area = L x H = 20 x 21 = 240 cm2
A right angle triangle
Area of right angle triangle = L x H divided by 2
20 x 21 = 240 divided by 2 = 120 cm2
Add both areas
240 + 120 = 360 cm2
Answer:
s = d/t and d = s × t
Step-by-step explanation:
s = d/t
d = s × t
