If you add everything up then
14x-2=180
14x=182
x= 13
 
So the angles would equal
2(13)+1= 27
3(13)-3= 36
9(13)= 117
The angles are 27 36 and 117
Which makes the smallest angle 27 which is B.

You first have to know that the measure of the three angles of a triangle= 180 add the terms and equal them to 180 2x+1 + 3x-3 =9x= 180 14x-2 = 180 14x= 182 x=13 This is not what you are looking for, you need to substitute 13 in the original measures 2 (13) +1= 27 degrees 3(13) -3= 36 degrees 9 (13) = 117 degrees therefore the smallest angle is 27 degrees if you add all three angle measure it will = 180 degrees Hope this helps you

Find the measure of stv in the figure
LUCKY_DIMON [66]

Answer:

STV = 153 degrees

Step-by-step explanation:

180 - 18 = 162 (angles on a straight line equal 180 degrees)

3q + 15q = 162

18q = 162

q = 162 / 18

q = 9

STV = 15q + 18

       = 135 + 18

       = 153

Hope this helps!

The interest that Cindy earns on her investment is given by the equation l = 42t where t is the time in years that her money is
alexandr1967 [171]
I = 42t

When t = 5,  I =  42*5  = 210

When t = 6,  I =  42*6  = 252

When t = 7,  I =  42*7  = 294

When t = 8,  I =  42*8  = 336

When t = 9,  I =  42*9  = 378

When t = 10,  I =  42*10  = 420

Thanks guys for the help. This one and one more and I’m done!
Karolina [17]

Answer: 60n^{3}

Step-by-step explanation:

To find the least common multiply, you must descompose 12 and 15 into their prime factors, as you can  see below:

12=2*2*3=2²*3

15=3*5

Choose the common and non common numbers with their greastest exponents:

3*5*2²=60

Now you must choose the common and non common variables with their greastest exponents:

n³

  Therefore, you can conclude that the least common multiply is:

60n^{3}
