Answer:
A. 280°
Step-by-step explanation:
Look at angles 1 and 2. Together, they form a straight angle. The measure of a straight angle is 180°.
We are told that the measure of <2 is 40°.
Since angles 1 and 2 together measure 180°, then the measure of <1 must be 140° since 180° - 40° = 140°.
Now we have m<1 = 140°.
Angles 1 and 6 are vertical angles. Vertical angles are congruent.
Therefore, m<6 = 140°.
We have m<1 = 140° and m<6 = 140°.
m<1 + m<6 = 140° + 140° = 280°

<span>Scientific notation is the way that scientists easily handle very large numbers or very small numbers. Scientific notation is written by writting a decimal number between 1 and 10 together with an exponent of 10.
Given

First, using distributive property of numbers, seperate the decimal numbers and the exponents of 10, we have

Because, scientific notation requires that the decimal number part be a number between 1 and 10, we move the decimal point 1 place foward and subtract 1 from the exponent of 10.
Therefore, </span><span>
