Question

Please Solve my math question please ​

Answer 1

Answer:

11cm

When we draw BY to AC

We will make a triangle BYC

In that triangle Y will be 90 degrees because BY is perpendicular to AC

In triangle BYC

YC=1/2AC

YC=4cm

Now we know that YC=4cm

And BC=12c

We want to find BY

In triangle BYC, since BY is leg, YC is leg and BC is hypotenuse

Therefore

(BY)^2 = (BC)^2 - (YC)^2

(BY)^2 = (12)^2 - (4)^2

(BY)^2 = 144-16

(BY)^2=128

BY = root square 128 = 11.313cm

Take these as notes:

(hypotenuse)^2 = (leg)^2  + (leg)^2

(Leg)^2 =  (hypotenuse)^2  - (leg)^2

After using the above fromulas, find the root square of the answer like we did with 128

If you found this helpful, plz mark as brainliest, if not please tell me the correct answer, I want to know too
