Answer:

50 degrees

Step-by-step explanation:

Since the two sides have the same length of 7 cm, it is an isosceles triangle so x = (180-80) / 2 = 50

What is the value of x in the equation 25x^2 = 16?
Lera25 [3.4K]

25x^2 = 16

divide each side by 25

x^2 = 16/25

take the square root of each side

sqrt (x^2) = +- sqrt(16/25)

x = +- sqrt(16)/sqrt(25)

x = +- 4/5

x = 4/5, - 4/5

soldi70 [24.7K]

Answer:

x = 1/2

y = 24

Step-by-step explanation:

y = 12 / x

y = 6 / x²

12 / x = 6 / x²

x² / x = 6 / 12

x = 1 / 2

y = 12 / x

y = 12 / (1/2)

y = 24

Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters and measure the duration of their fall. He
kotegsom [21]

<u><em>Answer:</em></u>

He would need to climb 480.97 m

<u><em>Explanation:</em></u>

The ground, the plane to climb and the altitude (100 m) all form a right-angled triangle

Therefore, we can apply the special trig functions.

<u>These functions are as follows:</u>

sin(θ) = \frac{opposite}{hypotenuse}

cos(θ) = \frac{adjacent}{hypotenuse}

tan(θ) = \frac{opposite}{adjacent}

<u>From the diagram, we have:</u>

θ = 12°

The distance that he needs to climb is the hypotenuse

The altitude = 100 m is the opposite

<u>Therefore, we can use the sin function as follows:</u>

sin(12°) = \frac{100}{hypotenuse}

hypotenuse = \frac{100}{sin(12)}

hypotenuse = 480.97 meters to the nearest hundredth

Therefore, he would need to climb 480.97 meters

Hope this helps :)
