question 5 qn 10 24201 previous qn next question miko loves drawing. she practises drawing every day. below are some of her drawings. find the total number of right angles in her drawings. drawings a, b, c, d, e blank right angles check answer

Explanation:

Step1: Analyze Drawing A

Drawing A (a hexagon - like figure with right angles). Let's count the right angles. Looking at the dots, we can see that Drawing A has 2 right angles.

Step2: Analyze Drawing B

Drawing B is a square - like figure (a rhombus with right angles, so a square). A square has 4 right angles. So Drawing B has 4 right angles.

Step3: Analyze Drawing C

Drawing C is a triangle. Let's check the angles. From the dot grid, we can see that Drawing C has 1 right angle (since it's a right - angled triangle).

Step4: Analyze Drawing D

Drawing D is a triangle - like figure. Looking at the dot grid, we can see that Drawing D has 1 right angle.

Step5: Analyze Drawing E

Drawing E is a triangle. From the dot grid, we can see that Drawing E has 1 right angle.

Step6: Sum up the right angles

Now, we sum the number of right angles from each drawing: \(2 + 4+1 + 1+1\)
First, \(2+4 = 6\), then \(6 + 1=7\), then \(7+1 = 8\), then \(8 + 1=9\).
