Answer:
Yes, right triangle
Step-by-step explanation:
Since it is a right triangle, we can use Pythagorean Theorem.
a^2+b^2=c^2
a and b are the legs, or shorter sides, and c is the hypotenuse, or the longest side.
We have 3 side lengths: 6, 8 and 10
6 and 8 are the shorter legs, so they are a and b.
10 is the longest leg, so it is c
Substitute the values into the equation, and see if it is true.
6^2+8^2=10^2
Evaluate the exponents
36+64=100
100=100
Since this is a true statement, these sides can make a right triangle.
Answer:
<u>x = 20</u>
Step-by-step explanation:
Given :
<u>1/4x - 3 = 2</u>
<u />
=============================================================
Add 3 to each side :
⇒ 1/4x - 3 + 3 = 2 + 3
⇒ 1/4x = 5
===========================================================
Multiply by 4 on each side :
⇒ 4 × 1/4x = 5 × 4
⇒ <u>x = 20</u>
