WebDec 14, 2024 · m∠B ≈ 73.74° m∠C ≈ 53.13° Step-by-step explanation: An altitude to AC bisects it and creates two congruent right triangles. This lets you find ∠A = ∠C = arccos(6/10) ≈ 53.13°. Since the sum of angles of a triangle is 180°, ∠B is the supplement of twice this angle, so is about 73.74°. m∠A = m∠C ≈ 53.13° m∠B ≈ 73.74° WebQuestion: Find m( bar(AB)) if m( bar(AC))=17cm isosceles triangle.

The curved surface of a well 15 m deep and having diameter 8 m is to be plastered. Find the total cost if rate of plastering is Rs 25 per m² WebApr 14, 2024 · 1. Let E be the midpoint of AC. Then ΔBCE is congruent to ΔMAE, and MA = BC = 5 cm. Then MD = 17 cm -5 cm = 12 cm. The height of the trapezoid is found from the Pythagorean theorem. If the center 5 cm of the trapezoid is removed, the remaining ends form an isosceles triangle with sides 10 cm and base 17 -5 = 12 cm. Its height in cm is Web= 2598 m 2. 10. ABC is a triangle in which AB = AC = 4 cm and ∠A = 90 0. Calculate the area of ABC. Also find the length of perpendicular from A to BC. Solution: It is given that. AB = AC = 4 cm. Using the Pythagoras theorem. BC 2 = AB 2 + AC 2. Substituting the values. BC 2 = 4 2 + 4 2. By further calculation. riw ticket nsw
