X is 73.you can make an equation to find x [tex]3x + 2x - 61 + x - 17 = 360 \\ 3x + 2x + x = 360 + 61 + 17 \\ 6x = 438[/tex][tex]x = \frac{438}{6} = 73[/tex]good luckReply
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
Set everything equal to 360:
(2x-61)+(x-17)+3x=360
6x-78=360
6x=282
x=47
X is 73.
you can make an equation to find x
[tex]3x + 2x - 61 + x - 17 = 360 \\ 3x + 2x + x = 360 + 61 + 17 \\ 6x = 438[/tex]
[tex]x = \frac{438}{6} = 73[/tex]
good luck
