A triangle has three angles 5x, 9x and 4x. as described below. Find the value of x and the value of each angle.

the value of x=10°

Step-by-step explanation:

hey there!

as there is given angles of the triangle i.e. 5x,9x,4x

now adding all of them,

5x +4x+9x=180 (reason: sum of angle of a triangle is 180°)

18x=180

x=180/18

x=10

therefore the value of x is 10

now the value of each angle is;

5x= 5*10=50

4x=4*10=40

9x=9*10=90

hope it helps! thank u!!!

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:
