In the figure, the measure of angle 7 is 57°. What is the measure of angle 8?

Answers

Answer 1

Answer:

Answer: The measure of angle 8 is 123° .

Step-by-step explanation:

Since we have given that

m∠7 = 57°

we have two lines intersecting each other at one point forming angles ∠7, ∠8, ∠5, ∠6.

So, Relation between ∠7 and ∠8 is linear pair.

And we know that ,

$\angle 7+\angle 8=180\textdegree\n\n57\textdegree+\angle 8=180\textdegree\n\n\angle 8=180\textdegree-57\textdegree\n\n\angle 8=123\textdegree$

Hence, the measure of angle 8 is 123° .

Answer 2

Answer: Angle (6) + Angle (7) = 180

Angle (6) + 57 = 180

Angle (6) = 180 - 57

Angle (6) = 123

------------

Angle (6) = Angle (8)

-----------

Therefore:

Angle (8) = 123 degrees

B: 4.8 centimeters
C: 5.6 centimeters
D: 7.6 centimeters
If anyone could help me, that would be great! This is the only question I'm actually stuck on.

Answers

The height of glass 1 which in cylindrical in shape is 7.6centimeters. Since the total volume of water added by Celia is 100 cubiccentimeter, and the volume of glass 2 is 26.4 cubic centimeter which is aconical in shape. Subtracting the volume of glass 2 from the total volume glass1 can be calculated and its height.

An average person's heart beats about 103,680 times a day. Write and solve an equation to find about how many times the average person's heart beats in one minute.

Answers

It should be noted that in each day there are 24 hours which in turn is comprised of 60 minutes each. The way to answer this item to properly do the conversion and the dimensional analysis.
1. The equation that would be used in order to find out how many beats in one minute does an average human's heart do is,
x = (103,680 times/day)(1 day/24 hours)(1 hour/60 minutes)Simplifying,
x = 72 times / minute
