Any suggestions on how to solve this? thanks
1 answer:
Answer: x = 4
Step-by-step explanation:
You basically want to solve for the angle A. Do arcsin of 1/3, which is approximately 19.47 degrees. In this triangle, we are missing the adjacent and opposite, but we do have the angle luckily. Lets use SOH-CAH-TOA.
We can see here that doing sine will give us the length of the opposite
. Do sine of 19.47, then multiply by 12. I got 4

Answer:
106.4622
Step-by-step explanation:
Given the information:
- A right triangle
- Leg lengths of
and
Use the pytagon theory to find the hypotenuse of the triangle
<=>
<=>
<=>
Take the square root of both sides
<=> c = 69.4622
=> expression in simplest form for the perimeter of a right triangle is:
+
+ 69.4622
= 27 + 64
+ 69.4622
= 106.4622
