Answer:
B. m∠B = 80°
Step-by-step explanation:
Supplementary angles are two angles that sum to 180°
⇒ m∠A + m∠B = 180°
⇒ 100° + m∠B = 180°
⇒ m∠B = 180° - 100°
⇒ m∠B = 80°
Knowing the value of each digit, we can arrange them from greatest to least like so:
11.771 > 11.717 > 11.171 > 11.117
I got 64,800 because you multiply 54,000 x 1.20 and that equals 64,800
In any rectangle, the area is given by the product of the width and the length.
Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:
