Question

draw a right angle triangle having hypotenuse of length 6.4 cm and one of the acute angle is 40 degree​

Answer 1

CONSTRUCTION OF RIGHT TRIANGLE HAVING HYPOTENUSE OF LENGTH 6.4 cm AND ONE OF THE ACUTE ANGLE 40°:

CALCULATION:

• Let AC be the hypotenuse, ∠C = 40° and ∠B = 90°.
• Given AC = 6.4 cm.
• From angle sum property we have,

              ∠A + ∠B + ∠C = 180°

              ∠A + 90 + 40 = 180

                   ⇒ ∠A = 50°

CONSTRUCTION:

• Draw a line segment AC = 6.4 cm.
• Mark a point Y from A at angle 50°.
• Draw ray AY.
• Similarly, draw another ray CX from C making an angle 40°.
• Let the point of intersection of AY and CX be B.
• ABC is our required right angle.
• You can verify that ∠ABC = 90°.
