Please help me! Find AC

1 answer:

8 0

We are asked to find the length of $AC$ , which measures $7x$ . Using the segment addition postulate, we can add the two given expressions for $AB$ and $BC$ and make it equal to the expression for $AC$ .
$AB + BC=AC$
$5x+1+15=7x$
$5x+16=7x$
$16=2x$
$x=8$
We've found the value of $x$ , but we aren't done yet. We need to plug in the value we got for $x$ into the expression for $AC$ , which is $7x$ . Therefore, $AC \Rightarrow7x\Rightarrow7(8)\Rightarrow\boxed{56}$ . Hope this helped and have a great day!

Answer:

72,90

Step-by-step explanation:

Since 9 is the biggest number so list multiples of 9 between 55- 101 range.

Which are 63, 72, 81, 90, 99. Any number that is a multiple of 9 is a multiple of 3 because 3x 3 = 9. 9 is a multiple of 3.

Any even number is a multiple of 2.

Only 72 and 90 are even numbers.

So 72 and 90 are numbers divisible by 2, 3, 9.

Mahala is making a piece of jewelry that is in the shape of a right triangle. The two shorter sides of the piece of jewelry are

Digiron [165]

The two "shorter" sides are referring to the legs of the triangles, because the hypotenuse is the largest side. Looking at this, we can find that it's a 3-4-5 triangle, which means that the scaling factor is 3, because 9/3 =3, 12/3=4, meaning we multiply 5 by 3 to get 15.
