please help me
The measure of the largest angle of a triangle is 90◦ more than the measure of the smallest
angle, and the measure of the remaining angle is 30◦ more than the measure of the smallest
angle. Find the measure of each angle. Show your work in obtaining your answer.

can you write equation to model this?

- anonymous

i dont know how

- anonymous

smallest = s
biggest = b
medium = m
b = s + 90
m = s + 30
s + m + b = 180
s + s + 30 + s + 90 = 180
3 s = 60 etc.....

what am i supposed to solve what equation

- anonymous

?

- anonymous

Do you want the equation or the answer?

- anonymous

i want the equation that im supposed to be solving in order to get the answer

- anonymous

is it system of equations?

- anonymous

I don't remember the exact equation, just what I wrote which is what my teacher had written down for me. The answers are S=60 M=30 B=90 that's the best I can do. Sorry

- anonymous

oh okay, thanks anyway

- anonymous

i still need help if you all know

- anonymous

what am i supposed to e solving

- anonymous

x+(x+30)+(x+90)=180
3x+120=180
3x=180-120=60
x=?

- anonymous

20

- anonymous

correct.

- anonymous

now find the other angles.

- anonymous

x+30=?
x+90=?

- anonymous

50 and 110?

- anonymous

correct

- anonymous

can you help me with another problem please?

- anonymous

sure,i will try.

- anonymous

do i post it here or new post?

- anonymous

anywhere

In each of the following systems of equations, look at the system and determine whether it
has infinitely many solutions, no solution, or one solution. Explain in each case how you
came to your conclusion. You should not attempt to solve any of the systems.
a) Let k represent a Real Number.
y = 2x + k
y = 2x − k
b) Let a represent a Real Number.
y = −4x + a
y= 1/4x-a
c) Let c represent a Real Number.
2x + 6y = 4c
3x + 9y = 6c

- anonymous

let us solve one by one
1
y=2x+k
y=2x-k
2x+k=2x-k
k=-k
k+k=0
2k=0
k=0
so if k=0
y=2x
has infinite solutions
case 2.if k not 0 ,then no solution.

- anonymous

wait so does it have infinite or no solutions

- anonymous

2.
y=-4x+a
\[y=\frac{ 1 }{ 4 }x-a\]
\[-4x+a=\frac{ 1 }{ 4 }x-a\]
multiply by 4
-16x+4a=x-4a
x=?
then y=?
only one solution in a
giving different values to a we can get different solutions

- anonymous

if k is 0 then infinite solutions
if k is non zero then no solution.

- anonymous

for A right

- anonymous

i think your problem want solutions with slope,
correct or not

- anonymous

he just wants us to state how many solutions each system of equations have

- anonymous

and why

- anonymous

i put A into the calculatior and it gave the ordered pair (8a/17,-15a/17)

- anonymous

2.
the lines are perpendicular so cut in only one point so only one solution
correct

- anonymous

wait what about A? it has one solution?

- anonymous

3.divide 1st eq. by 2 and 2nd by 3

- anonymous

how can i divide one equation by the other?

- anonymous

i am talking about 3rd question.

- anonymous

yeah

- anonymous

nevermind this question has got me so confused

- anonymous

thanks for your help tho

- anonymous

x+3y=2c
x+3y=2c
so practically both are same
and 3y=-x+c
giving different values to x we get different solutions
so it has infinite solutions.

- anonymous

so a and b have only one solution and c has infinite?

- anonymous

a.
if k is non zero then no solution

- anonymous

okay

- anonymous

thanks so much

- anonymous

only b has one solution.

- anonymous

c has infinite solutions.

- anonymous

okay thank you

- anonymous

if k is non zero a has no solution.

- anonymous

yw

- anonymous

i am leaving now..Good night.

- anonymous

take care@surjithayer
