If the weight of the little brother is x, then the weight of Charles is x + 9
The equation that can be used to determine what each one weighs is:
x + (x + 9) = 99.
Let us now solve it.
x + x +9 = 99
2x + 9 = 99
2x = 99 - 9
2x = 90
x = 90/2
x = 45
Little brother's weight is 45 kg.
Charles' weight will be 45 + 9 = 54 kg
Adding these two weights will give 99kg

Answer:
∠XWY = 58°
∠YXZ = 32°
∠WVZ = 116°
∠XWZ = 90°
∠XZY = 58°
Step-by-step explanation:
Triangle VWX is isosceles. Its base angles are (180° -64°)/2 = 58°.
∠XWY = 58°
The other corner angles are the complement of this.
∠YXZ = 32°
The obtuse angles at V are the supplement of the one marked
∠WVZ = 116°
We assume the figure is a rectangle, so each full corner angle is a right angle.
∠XWZ = 90°
The remaining angle of interest is congruent to the first angle of interest.
∠XZY = 58°
