If B lies along the positive x-axis, then the coordinate of B is (12, 0). Since the right angle is at B and BC is 5, it means that C is 5 units above B.
Therefore, the coordinate of C is (12, 5)
A square pyramid is a pyramid that has a square as its base.Thus, its sides are composed of 4 triangles.
We need to get the area of the square and the triangles to get the total surface area.
Square sides = 4 cm.
triangle: base = 4cm ; height = 4.5
Area of the square = s² = (4cm)² = 16 cm²
Area of the triangle = hb/2 = 4.5cm(4cm) /2 = 9 cm²
9 cm² x 4 triangles = 36 cm²
Total area = 16cm² + 36cm² = 52 cm² is the area of the required mesh to create the tea bag.
Answer:
Total students that failed in both subjects would be 10
Step-by-step explanation:
Students that passed English : 70 - 40 = 30
Students that passed Hindi : 80 - 40 = 40
Total students that passed both subjects 110 (40 + 40 + 30)
120 - 110 = 10 students failed in both subjects
The 30 & 40 come from the students that passed each subject above, then the extra 40 comes from the amount of students that passed both.
