Answer 1

Answer:

Step-by-step explanation:

if u want clear solution whatsapp me on 7836030983 Because i forget to put picture.........

there is no option to send pic

.. let upper part from point that broken is x and

then lower will 90-x

sinA= (90-x)/x

cosA= 27/x

squaring and adding equation 1 and 2

sin^2A+cos^2A={(90-x)^2/x^2}+ 27^2/x^2

1 = [{8100-180x+x^2}÷x^2]+[ {729}÷x^2]

1 = [8100+729-180x+x^2]÷x^2

x^2=8829-180x+x^2

x^2 will cancel out because both side have x^2 of same sign

then

180x=8829

x=49.05 cm

hence height from ground to broken point = 90-49.05 = 40.95 cm
