Set up an equation:
45 = 4x +5 Subtract 5 from both sides.
40 = 4x Divide by 10 on both sides
10 = x.

If the sister is 20 now, the brother is 10. do you understand?
Answer:
38 cm²
Step-by-step explanation:
The shaded shape is composed of two rectangles.
A horizontal rectangle at the top of the T shape and a vertical rectangle.
area of horizontal rectangle = 2 × (2 + 3 + 5) = 2 × 10 = 20 cm²
area of vertical rectangle = 3 × 6 = 18 cm²
shaded area = 20 + 18 = 38 cm²
Answer:
∠QDP = 34°
Step-by-step explanation:
The complete question is shown in the image attached.
In triangle ABC, ∠ABC = 90° and ∠BCA = 28°. Hence:
∠CAB + ∠ABC + ∠BCA = 180° (sum of angles in a triangle)
∠BCA + 28+ 90 = 180
∠BCA + 118 = 180
∠BCA = 180 - 118
∠BCA = 62°
Also ∠DCA + ∠BCA = 90° (Each angle in a rectangle is 90°)
∠DCA + 62 = 90
∠DCA = 90 - 62 = 28°
∠DAC + ∠BAC = 90 (angle in a rectangle)
∠DAC + 28 = 90
∠DAC = 90 - 28 = 62°
In triangle ADQ, ∠DQA = 90° and ∠QAD = 62°. Hence:
∠QAD + ∠ADQ + ∠QAD = 180° (sum of angles in a triangle)
∠ADQ + 62+ 90 = 180
∠ADQ + 152 = 180
∠ADQ = 180 - 152
∠ADQ = 28°
In triangle DPC,DP = PC, hence ∠PDC = ∠DCP= 28°.
∠PDC + ∠ADQ + ∠QDP = 90° (angle in a rectangle)
28 + 28 + ∠QDP = 90
∠QDP + 56 = 90
∠QDP = 90 - 56
∠QDP = 34°
