Question

construct a right angle triangle ABC in which hypotenuse BC=10.5 cm and side AB= 7.3 cm

Answer 1

Answer:

angle BC = 7.56 cm

Step-by-step explanation:

Here the angle A is at the vertex and angle B and C are the arms of the triangle. So here angle AB will be taken as length.

hypotenuse (BC) = 10.5 cm

side(AB) = 7.3 cm

hyp^2 = l^2 + b^2

10.5^2 = 7.3^2 + b^2

110.5 = 53.29 + b^2

110.5 - 53.29 = b^2

57.21 = b^2

b = √57.21

b = 7.56 cm

Now construct the triangle according to the lengths given in the question using a scale by putting a straight line or use a protractor to draw 90 degree. Here u can take 7.56cm as 7.5 cm
