Total measure of the triangle is 180
So you set the equation equal to 180 and then solve for x using basic calculation

13x=115
X=8,85

siniylev [52]

Answer:

4y= -x - 28

Step-by-step explanation:

the products of the gradient of parallel lines is 1

m1 x m2=1.......(1)

8-4x=0

re-arranging we have

0=-4x +8

comparing with y=mx +c we have

m1=-4

put the value of m1 in eqn 1

-4 xm2 =1

m2 =-1\2

from the relation.....

m=y-y1\x-x1

put the value of m1 above

-1\2=y-(-9)\x-0

cross multiply

-1(x-8)=4(y+9)

-x +8=4y+36

re-arranging we have

4y=-x-36+8

4y=-x-28//

A. Every month Population will increase by a factor of 0.84%.

B.  Every 3 months Population will increase by a factor of 2.5%.

C. Increase in population in every 20 months is 10% + 6.72% = 16.72%.

<u>Step-by-step explanation:</u>

Here, we have  number of employees in a company has been growing exponentially by 10% each year. So , If we have population as x in year 2019 , an increase of 10% in population in 2020 as  x + \frac{x}{100}\times10 which is equivalent to \frac{11x}{10}.

<u>A.</u>

For each month: We have 12 months in a year and so, distributing 10% in 12 months would be like \frac{10}{12}  = 0.84 . ∴ Every month Population will increase by a factor of 0.84%.

<u>B.</u>

In every 3 months: We have , 12 months in a year , in order to check for every 3 months  \frac{12}{3} = 4 and Now, Population increase in every 3 months is \frac{10}{4}  = 2.5.  ∴ Every 3 months Population will increase by a factor of 2.5%.

<u>C.</u>

In every 20 months: We have , 12 months in a year in which increase in population is 10% . Left number of moths for which we have to calculate factor of increase in population is 20-12 = 8. For 1 month , there is 0.84% increase in population ∴ For 8 months , 8 × 0.84 = 6.72 %.

So , increase in population in every 20 months is 10% + 6.72% = 16.72%.

What is measurement angle C?<br>​
11Alexandr11 [23.1K]
So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)
