The sum of any interior angle with each exterior angles is always 180, and the sum of all the exterior angles in a polygon is always 360
if angle z= 64, its exterior angle is 116 degrees (180-64=116)
now knowing two of the exterior angles and the fact that the sum of the three is 360
360 - 116 - 103 = 141
x = 141 degrees

Alexxx [7]

Hi,

Let  the

Youngest brothers age = x+2

Middle brothers age = x+4

Oldest brothers age = x+6  

So,

Youngest brothers age = x+2 = 28+2 = 30 years of age

Middle brothers age = x+4 = 28+4 = 32 years of age

Oldest brothers age = x+6 = 28+6 = 34 years of age

Have a great day!

Musya8 [376]

Answer:

6 hot dogs, 2 drinks

Step-by-step explanation:

let y = number of hot dogs

let x = number of drinks

system:

y = 3x

4.5y + 2.25x = 31.50   (standard form:  y = -1/2x + 7)

if you graph the system, lines intersect at (2, 6)

I need help with this question​
Artyom0805 [142]

Answer:

Step-by-step explanation:

It's algebra really, basically make a system of equations.

1b+5j=t

3b+2j=2t

I'm gonna solve the first one for buckets so we have it in terms of jars.

b+5j=t

b=t-5j

Now I plug that into the other equation

3b+2j=2t

3(t-5j)+2j=2t

3t-15j+2j=2t

Now, since it wants how many jars are in one tub, I want to solve it so there's 1t on one side of the equation and all js on the other.  or it other words solve for t.

3t-15j+2j=2t

3t-13j = 2t

3t = 2t+13j

t = 13j

So it takes 13 jars to make one tub, or one jar is 1/13 of a tub.  You could then plug that in to one of the equations and find how much a  bucket is.
