Question

draw a right angled triangle having hypotenuse of length 8.1 cm and one of the acute angles of measure 50°​

Answer 1

$90 - 50 = 40$

In a right angle triangle we know

it have a right angle (90°) .

According to the question given an other angle is 50°

then another angle is 40°.

First u draw 8.1cm

then draw 50° and 40° respectively two side of 8.1 cm

Answer 2

1)Draw side BC of any length.  

2)From point C using protractor make an angle of 50 degree.

3) Take a length of 8.1 cm and cut an arc from point C

4) AC is the hypotenuse and point C is 50 degree and point B is 90 degree

5)hence, ΔABC is a right angled triangle
