This is simple. If you add 5 and 8 together, you get 13. What you do, is add the 1 to the 2, you get 3. The 3 in the 13 stays the same, so the awnser is 33.
Answer:
12
Step-by-step explanation:
For these problems you should use the pythagorean theorem: a^2+b^2=c^2
In this case, 13=c and 5=a
so:
5^2+x^2=13^2
25+x^2=169
subtract 25 from both sides
x^2=144
√144=12
missing side=12
Answer:
16
Step-by-step explanation:
AC= 15x+2
BD= 9x+14
AE= 1/2AC
AC=BD
1) First we must find what x is. Because AC and BD are the same length, we can set them equal to each other to find x.
15x+2=9x+14
6x=12
x=2
2) Now that we know x, we plug the value for x back into the equation for AC.
AC=15x+2
AC=15(2)+2
AC=30 +2
AC= 32
3) Finally, we can find AE because it is half of AC.
AE=1/2AC
AE=1/2(32)
AE=16
hope this helps!! :)
