Answer:
a common denominator for 3/7 and 1/3 is 21
Answer:
<h2>x = 3, y = 2</h2>
Step-by-step explanation:


<span>In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The shorter leg is </span>the side opposite the 30 degree angle, therefore
the shorter leg = 30/2 = 15
<span>By the Pythagorean theorem
</span><span>the longer leg = </span>√(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units
Answer:
r=8
t=4√29
Step-by-step explanation:
By the altitude leg theorem:

This implies that:

We simplify to obtain:

By the Pythagoras theorem:
