Answer:

x = 5

Step-by-step explanation:

Since the triangle is isosceles, the height is cutting the base in half.

That means the 2 right triangles have sides of 3 and 4.

The 3rd side is x. Using the Pythagorean Theorem, you get 5.

It is a 3-4-5 triple.

The previous response is wrong because it is isosceles, not equilateral

What is the measure of x? Please help!

Zepler [3.9K]

Answer:

x =√[y²+(27)²] = √[ z² - 3² +(27)²]

Step-by-step explanation:

step 1) x=√[y²+(27)²]

step 2)

We find y

z²=y²+3² → y² = z² - 3²

step 3) x = √[ z² - 3² +(27)²]

Step-by-step explanation:

<u>Trigonometric Ratios </u>

The ratios between the sides of a right triangle are called trigonometric ratios.

If any of the acute angles is chosen as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.

The image shows a right triangle with a tree and the ground forming a right angle and an elevation angle of 33°.

This angle of 33° has a side of 30.5 m as its adjacent leg and the height of the tree X as the opposite side.

The trigonometric ratio that relates both legs is the tangent:

$\displaystyle \tan 33^\circ=\frac{X}{30.5}$

Solving for X

$X=30.5\cdot \tan 33^\circ$

Using a calculator:

X = 19.81 m

The height of the tree is 19.81 m
