The vertex angle of an isosceles triangle measures 42°. a base angle in the triangle has a measure given by
(2x + 3)". what is the value of x? what is the measure of each base angle?
each base angle measures

they are simplified

step-by-step explanation:

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:
