(HELP) The provided diagram of triangle ABC will help you to prove that the base angles of an isosceles triangle are congruent.
The first step is to draw auxiliary line AO. What must be true about AO in order to complete the proof using the ASA
(Angle Side Angle) triangle congruency theorem? Classify each statement as needed or not needed to complete the
proof
AO bisects < BAC
AO is perpendicular to BC
Point O is the midpoint of BC
AO is an altitude

jk it's 20

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:

correct answer was 0.5

more i think

hope this !
