Answer:
The angle for the top of the triangle is 79. For the right corner would be 56. Then going to the bottom of the blue triangle vertice would be 75. The missing angle next to that one would be 55/
Step-by-step explanation:
Remark
You could solve it using logs. Either base will do. They both will give you the same answer (I'll put the second solution before the first one).
Step one
Take the log of both sides.
Log 37^x = log 12
Step Two
Using the power rule for logs, multiply x by the log(37)
x*log(37) = log (12)
Step three
Divide both sides by the log(37)
x = log(12) / log (37)
x = 1.079 / 1.568
x = 0.6882 <<<<< Answer
Use ln
ln 37^x = ln12 Take ln of both sides.
x*ln(37) = ln(12) Multiply x (the power by ln(37)
x = ln(12) / ln(37) Divide by ln(37)
x = 2.485 / 3.611
x = 0.6882
You should be able to put the sentences together just the way I've done it.
6.
original=100%
75% off means
100%-75%=25%
remaining is 25%
it was sold for 45
therfor
25%=45
find 100%
just multipl it by 4 since 25 times 4=100
100%=45 times 4=180
originl price=180
answer is A
7. simle interest
I=PRT
P=principal=1000
I=interest=300
T=time=5
R=rate in percent form=?
300=1000*?*5
300=5000?
divide both sides by 5000
0.06=?
aka
6%
answer is 6%
b is answer
6. A
7. B
