Answer:
The measure of angle a is 35 degrees, b is 55 degrees and c is 110 degrees.
∡a has an angle of 40°. Vertical angles are always congruent.
∡b is the 3rd angle in a triangle, the other two are 40° and 90° all of the interior angles in a triangle add up to 180°.
∡c is a linear angle, linear angles always add up to 180°.
Answer: They are proportional.
Explanation: To determine whether a table is proportional just simply notice if there is a number you can get to the next number.
Example: on the x values you multiply from left to right by 2 and get the next number. on the y values you multiply by 1. This table is proportional
Answer:
Standard form would just be 1,000,000 but in scientific notation, it would be 1 x 10 to the power of 6.
Step-by-step explanation:
First flip the second fraction and multiply, also factor out smaller "pieces" of the expressions (for example, the top left can have an x factored out) and cancel any like terms
