Answer:
C ≈ 22.1°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle.
Then we have ...
C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)
C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.
Answer:
B. Yes, the surface area of Earth is only 1.1 times the surface area of Venus.
Step-by-step explanation:
We have been given that the surface area of Venus is 460,230,000 km2 whereas Earth is .
We can see that area of Earth is given in scientific notation and area of Venus is given in standard form, so first of all let us convert area of Earth in standard form.
To compare our given surface areas we can set an equation as:
Upon rounding our answer to nearest tenth we will get,
Therefore, the surface area of Earth is only 1.1 times the surface area of Venus and option B is the correct choice.
Answer:
D.
Step-by-step explanation:
A and B aren't correct because the last term is negative.
The factored form of D is

Answer:
-3/2, -3/5, 3/5, 3/2
Step-by-step explanation:
-3/2 Is The Leastest Number Beacuse It Has A Negative Number And -3/2 = -1.5
-3/5 Is The Second Least Number Because -3/5 > -3/2, It Is Also A Negative As Well As -3/2
3/5 Is The Second Greatest Number Because It Is A Positive Number And 3/5 = 0.6
3/2 Is The Greatest Number Because 3/2 > 3/5, It Is Also A Positive Number As Well As 3/5.
Answer:
X=-5
Step-by-step explanation:
√4x+8=x+3
Simplifies to:
2x+8=x+3
Let's solve your equation step-by-step.
2x+8=x+3
Step 1: Subtract x from both sides.
2x+8−x=x+3−x
x+8=3
Step 2: Subtract 8 from both sides.
x+8−8=3−8
x=−5
