Answer:
Step-by-step explanation:
Three times a number x : 3x
Three times a number x increase by 4: 3x +4
Five times the number x: 5x
5x = 3x +4
Subtract 3x from both the sides.
5x - 3x = 3x +4 - 3x
2x = 4
Divide both sides by 2
2x/2 = 4/2
x=2
The number is 2
It's an isosceles triangle, which means base angles are equal.
48 = 6x
48/6 = x
8 = x
48 = 48
Angle y = 180° - (48° + 48°)
Angle y = 180° - 96°
Angle y = 84°
The two missing angles are 48° and 84°.
