In a 30°-60°-90° triangle, the length of the hypotenuse is 30. Find the length of the longer leg.

1 answer:

6 0

In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The shorter leg is the side opposite the 30 degree angle, therefore
the shorter leg = 30/2 = 15

By the Pythagorean theorem
the longer leg = √(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units

erik [133]

Answer:

842 grams

Step-by-step explanation:

$70\frac{1}{6} =\frac{421}{6}$

$\frac{421}{6} *12\\\\842$

One cake consists of 421/6 grams of chocolate.

Since Sally wants to give 1 cake to 12 friends, we multiply 421/6 and 12.

To make 12 cakes, she needs 842 grams of chocolate.

How do I find the value of x for a pair of congruent triangles

Andreyy89

Hi there!

For congruent triangles, all angle measures and sides are congruent. So, if you look at the other triangle, and find the corresponding side, it will be the same measure.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
