Answer:
134 degrees
Step-by-step explanation:
a triange has a total of 180 degrees
this means the 2 angles in the are equal to
180-(last angle)=x+102
the exterior angle is also 180-(last angle)
thus you can set the two equal to each other
(4x+6)=x+102
move 6 and x
3x=96
x=32
plug in
(4(32)+6)=134
to check
180-134=46(last angle of the triangle)
32+102+46=180 (true)
