Answer:
x = 64°
y = 71°
Step-by-step explanation:
✔️x = 180 - 2(58) (isosceles triangle)
x = 180 - 116
x = 64°
✔️y + 45° + x = 180° (angles on a straight line)
y + 45° + 64° = 180° (substitution)
y + 109 = 180°
y = 180° - 109°
y = 71°
Answer:
The number of sides is 3 on each piece of paper, altogether there are 6 sides.
The total number of angles on a triangle is 180°, altogether the sum of both triangles is 360°
Answer:
x=-4
Step-by-step explanation:
Set both equations equal to each other.
x +11=3x+19
solve for x.
11 as a decimal would be : 11.0
1/6 as a deximaal would be : .166667
