A = 1/2 bh
A = 1/2 (21)(8)
A = 1/2 (168)
A = 84
Answer:
y - 2 = 5(x+1)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
y - 2 = 5(x- -1)
y - 2 = 5(x+1)
28.49 because they dont have a proportion
Answer: Incorrect
Step-by-step explanation:
Given
Gavin and his three friends wants to share of cake equally.
So, there are 4 members to distribute the cake
Each member will get
So, each member get one-twelvefth of the given cake.
Hence, Gavin is incorrect.
see the attached figure to better understand the problem
we know that
The equilateral triangle has three equal sides
so
in the equilateral triangle ABC
the height of the triangle is the segment BD
in the right triangle BCD
Applying the Pythagorean Theorem
solve for BD
substitute the values
therefore
<u>the answer is</u>
the height of the triangle is
