A triangle has one angle measuring 3x degrees.A second angle is 2x+20 degrees and the third angle measures 4x-20 degrees. What i
S_A_V [24]
<span>It is important to know that the sum of the three angles inside a triangle add up to 180 degrees. So then we get the following by adding up all three provided angle measures: 3x + (2x + 20) + (4x - 20) = 180 Some algebraic manipulation follows: 3x + 2x + 20 + 4x - 20 = 180 9x = 180 x = 180/9 = 20 The value of x is 20 degrees.</span>

Calculs from the north you walk 1 mile and a temperature was 5 degrees from the west you walk 1 mile and the temperature change
MakcuM [25]

Answer: 6.4 degrees

Step-by-step explanation:

a= 5 degrees temperature difference to the north gives the opposite of the triangle,

b = 4 degrees temperature difference to the west gives the adjacent,

c = temperature difference of 1 mile to the south east gives the hypotenuse.

Therefore,

Using Pythagoras equation,

c² = b² + a²

c = sqrt( 5² + 4²)

c = sqrt(41) = 6.4 degrees

Therefore, there will be 6.4 degrees temperature difference 1 mile to the south east

you have a full job that pays 2400 per month you decide to take a part time job delivering newspapers that pay 200 per week if 1
lana [24]
Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640
