Answer:
Jumper, y = 172
Shirt, x = - 105
Step-by-step explanation:
Let :
Shirt = x
Jumper = y
5x + 4y = 163 - - (1)
3x + 2y = 29 - - - (2)
Multiply (1) by 3 and (2) by 5
15x + 12y = 489 - - - (3)
15x + 10y = 145 - - - (4)
Subtract :
12y - 10y = 489 - 145
2y = 344
y = 344 / 2
y = 172
Put y = 172 in (3)
15x + 12(172) = 489
15x + 2064 = 489
15x = 489 - 2064
15x = - 1575
x = - 105
The values ;
Jumper, y = 172
Shirt, x = - 105
We weren't supposed to obtain a negative value, kindly check if the parameters given are correct.
In the triangle ABE
step 1
Find out the measure of angle AEB
m by form a linear pair
mm
step 2
Find out the measure of angle ABE
m by alternate interior angles
step 3
Find out the measure of angle x
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
msubstitute given values
x+100+30=180
x=180-130
<h2>x=50 degrees</h2>
Small triangle : (1,4), (3,1), (3,4)
The x: (3,2)
The big triangle: (-3,3), (-1,5), (-2,1)
(For the big triangle that is only correct if the black dot is the mirror line)
2(2x+1)= (2 x 2x) + (2 x 1) = 4x + 2
