Answer:
Step-by-step explanation:
if you know that the perimeter is 20,
then you have to divide by 4 to get the length of one side
20/4=5.
Draw the diagonal and write in it's length as x.
Use Pythagorean formula
Then know that a2+b2=c2
and use the two side lengths as a and b.
This gives you the equation
5^2+5^2=x^2.
Do the calculations and solve the equation.
25+25=x^2
50=x^2
√50=x.
Therefore x=√50 where x equals the length of the diagonal.
The answer is D, good night
Answer: 41.16 cm cubed.
= (0.5 • 4.2 • 2.8) • 7 = 41. 16
Explanation: B = 1/2 base times hight of the triangle. Not the figure.
Remember the figure is also tipped over, and its not up right. So you’ll have to try to imagine and image it standing up right.
In reflection, translation and rotations the pre image and the image are congruent and in dilation they are similar <span />
The solution is the set of numbers that can be written in place of
all the variables and make all of the equations true.
If you're asking for the actual numbers, there's nobody in the world
who could find those without seeing the system of equations.
