Answer:

C. 107°

Step-by-step explanation:

Since angle 7 and 73° are the same angles, and angle 7 and angle 8 are supplementary, then we just need to subtract 180 - 73.

180 - 73 = 107

Answer:

540 mins | 9 hours | 540, 9

420 mins | 7 hours | 420, 7

300 mins | 5 hours | 300, 5

180 mins | 3 hours | 180, 3

Step-by-step explanation:

1 hour = 60 mins

To convert hours into minutes, multiply the number of hours by 60 minutes:

9 hours × 60 mins = 540 mins

7 hours × 60 mins = 420 mins

5 hours × 60 mins = 300 mins

3 hours × 60 mins = 180 mins

Which of the following could be the ratio between the lengths of the two legs of a 30-60-90 triangle?
Artist 52 [7]

Answer:c

options A  and B

Step-by-step explanation:

the ratio between the lengths of the two legs of a 30-60-90 triangle

General ration of 30-6- 90 degrees triangle is

x : xsqrt(3) : 2x

When x=1 the ratio becomes 1 : 1 sqrt(3)

when x= 2sqrt(3) the ratio becomes

It becomes

Two sides of 30-60-90 triangle cannot be equal

so option c  and option D are not possible

sqrt(2) is also not possible  because we have sqrt(3) in general ratio

How do you solve: 2(7-x)+4x=20
Angelina_Jolie [31]
First expand it
Next subtract 14 - 2x + 4x so it can be 14 + 2x
Next subtract 14 from both sides
Next subtract 20 - 14 so it can be 6
Then divide both sides by 2
And lastly reduce the fraction 6/2 and once u reduce it u have your answer which is x = 3.
