Answer:
0.6 i think ...
Step-by-step explanation:
it means that the length is 5 times the width
a) To find the missing side length on triangle A, we can use the Pythagorean theorem.
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5 cm
5 and 12 = 5 and 12
b) The two triangles are congruent because they have two side lengths in common. If at least two side lengths are the same on two triangles, then they are congruent. In addition, these triangles have one angle in common as well.
Hope this helps!! :)
The solution set for the both equation is (3,0) and (-1,0)
We have given that the equation

We have to determine the solution to the first equation
<h3>
What is the quadratic equation formula?</h3>





Now use this value we have to find the value of y
When x=3 then
y=(3)^2-2(3)-3
y=9-6-3
y=0
When x=-1 then y=1-2(-1)-3
y=1+2-3
y=0
Therefore the solution set for both equations is (3,0) and (-1,0).

Answer:
≈ 5.36
Step-by-step explanation:
If we have a triangle in which the angle measure of it being broken down are the same, that means that the legs in which the angle measures are the same will have the same length.
If we already know that DE ≈ 9.28, then we can subtract this from 20 and divide by two to get BD, which is equal to EC.

However, I'm not 100% sure about this answer.
Hope this helped (and I hope I'm right)
