Answer:
c = 60.65 cm
Step-by-step explanation:
Given that,
The two sides of a triangle are 33 cm and 37 cm.
The angle between these two sides is 120°.
We need to find the length of the third side of the triangle. Let c is the third side. Using cosine rule,
a = 33 cm, b = 37 cm and C is 120°
So,
So, the length of the third side of the triangle is 60.65 cm.
Lets try substitution5x+2y=21=5x=21-2y=x=(21-2y)/5
sub into second equation
-2(21-2y)/5+6y=-34(-42+4y)/5+6y=-34solve for yy=-64/17plug into equation and solve for x=(97/17)
Answer:
Step-by-step explanation:
8x+5=29, x=3
subtract 5 on each side
8x=24
then divide by 8 on both sides to isolate x
x=3
Answer:
About 220 minutes.
What you have to do is divide 17 by 12 and multiply it by 155. After that, round the decimal up since the decimal part still counts as time.
Determine the percent of book she hasn't read.percent = 100% - percent she has read
percent = 100% - 34%
percent = 66%
She hasn't read 66% of the book.
Find the amount of page she hasn't read.page =
page =
page =
page =
page = 165
The number of page she hasn't read is 165. It's more than 125.
