If the leg of a triangle is 4 and the hypotenuse is 10 what is the number of the other leg

Given - One leg of a triangle is 4

hypotenuse is 10

To find - Other leg

Solution -

Using Pythagoras Theorem

(4)^2 + (x)^2 = (10)^2

(x)^2 = (10)^2 - (4)^2

(x)^2 = 100 - 16

x^2 = 84

x= root 84

x = 2 × root 3 × 7

x = 2 root 21

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
