The third angle is 56 degrees because it is a right <u>triangle</u>, so the three angles will add up to 180 degrees. Since it is a right triangle, you know one angle is 90 degrees. All you have to do is add 90 and 34, and then subtract that from 180 to get your third angle.
Slope between two points =
(Change in y) / (change in x) .
For these points, that's -7/5 .
Answer:
Can you show me the fourth choice? I will be able to answer once you post it. If this is a four choice problem, then it is the choice that I can not see.
Step-by-step explanation:
According to rules of logs, ln(x+1) - ln 3 = ln [(x+1)/3].
x+1
Then your equation becomes ln [ ------------- ] = 8
3
Write the new exponential equation e = e.
Raise the "e" on the left to the power ln [(x+1)/3]. Raise the "e" on the right to the power 8. We get:
x+1
--------- = e^8
3
Then x+1 = 3e^8, and x = 3e^8 - 1 (answer)
Answer:
x=46
Step-by-step explanation:
add the 2 equations and set them equal to 180, and then do the math from there.
