Statement Reason
1. Let points A, B, and Cform a
triangle
given
2. Let De be a line passing
through B, parallel to AC,
with angles as labeled
defining a parallel line and labeling angles
3.
4.m_1 = m 4, and
m23 = m25.
Congruent angles have equal measures.
5.m24+ m2 2 + m25 = 180°
angle addition and definition of a straight angle
6. m_1 + m22 + m23 = 180°
substitution
What is the missing step in this proof?

sorry not sure c

Step-by-step explanation:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

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:
