Let us consider a 30°-60°-90°△ABC right angled at B in which ∠C = 30⁰ and ∠A = 60⁰ with hypotenuse AC = 10√2 units.

Solution:-

In △ABC,

$\longrightarrow$ sin ∠C = $\sf \dfrac{Perpendicular}{Hypotenuse}$

$\longrightarrow$ sin ∠C = $\sf \dfrac{AB}{AC}$

$\longrightarrow$ sin 30⁰ = $\sf \dfrac{AB}{10\sqrt{2}}$

$\longrightarrow$ $\sf \dfrac{1}{2}= \dfrac{AB}{10\sqrt{2}}$

$\longrightarrow$ $\sf AB = \dfrac{10\sqrt{2}}{2}$

$\longrightarrow$ $\sf AB = 5\sqrt{2}\:units$

$\\$

In △ABC,

$\longrightarrow$ cos ∠C = $\sf \dfrac{Base}{Hypotenuse}$

$\longrightarrow$ cos ∠C = $\sf \dfrac{BC}{AC}$

$\longrightarrow$ cos 30⁰ = $\sf \dfrac{BC}{10\sqrt{2}}$

$\longrightarrow$ $\sf \dfrac{\sqrt{3}}{2}= \dfrac{BC}{10\sqrt{2}}$

$\longrightarrow$ $\sf BC = \dfrac{10\sqrt{2}\times \sqrt{3}}{2}$

$\longrightarrow$ $\sf BC = \dfrac{10\sqrt{2\times 3}}{2}$

$\longrightarrow$ $\sf BC = \dfrac{10\sqrt{6}}{2}$

$\longrightarrow$ $\sf BC = 5\sqrt{6}\: units$

Thus , the length of other two sides of triangles are 5√2 and 5√6 units.

If the hypotenuse of a 30°-60°-90° Triangle is 10√2, find the length of the other two sides.

A)The angles are 30-60-90. The longest leg (hypotenuse) of the triangle is twice the shortest leg. The middle leg is the shortest leg times the square root of 3.

Step-by-step explanation:

The answer choice speaks for itself.

The legs of a 45-45-90 triangle have the ratios 1 : 1 : √2.

The legs of a 30-60-90 triangle have the ratios 1 : √3 : 2.

Clearly, the given leg lengths match the second set of ratios more closely:

10 : 17.32 : 20 ≈ 1 : √3 : 2.

Option A is right

Step-by-step explanation:

Given is a triangle (right angled) with other degrees as 30 and 60.

The length of hypotenuse = 30

We have to find the length of shorter leg.

We know that in a 30-60-90 triangle, the length of shorter side is always half the length of the hyptenuse.

In 30-60-90 triangle, opposite side of smaller angle/hypotenuse =1/2

Using the above we get

the shorter side = 1/2 (hypotenuse) = 1/2(30) = 15

Hence answer is 15

Step-by-step explanation:

Question 6)

sin Y= m

sin Y = m/1

So, hypotenuse is 1

Since sine is opposite over hypotenuse

So XZ= m and YZ = 1

Similarly, cos Y = k

cos Y = k/1

So adjacent side of angle Y is k

So XY = k

cos z - sin z = $\frac{XZ }{YZ } - \frac{XY}{YZ}$

cos z - sin z = $\frac{m }{1 } - \frac{k}{1}$

cos z - sin z = m - k

Question 7)

the relationship between sine, cosine, and tangent.

tan(x) = sin(x)/cos(x) = (11/61)/(60/61)

tan(x) = 11/60

Question 8)

Start with where the shorter leg is. It must be opposite the smallest angle.

In a 30 - 60 - 90 degree triangle you have the hypotenuse to be twice as long as the shortest side. You have to read that a couple of times to make sure you understand it.

That being said, if the shortest side is x, the hypotenuse will be 2x.

Since in this case the shortest side is 11, the hypotenuse will be 2*11 = 22

The answer is 22
