Answer:
Hence proved △ABE∼△CBF.
Step-by-step explanation:
Given,
ABCD is a parallelogram.
BF ⊥ CD and
BE ⊥ AD
To Prove : △ABE∼△CBF
We have drawn the diagram for your reference.
Proof:
Since ABCD is a parallelogram,
So according to the property of parallelogram opposite angles are equal in measure.
⇒1
And given that BF ⊥ CD and BE ⊥ AD.
So we can say that;
⇒2
Now In △ABE and △CBF
∠A = ∠C (from 1)
∠E = ∠F (from 2)
So by A.A. similarity postulate;
△ABE∼△CBF
Answer:74.55 beat per minute
Step-by-step explanation:
Given
Heart beat is 52 beat per minute
i.e. beat per sec
If heart rate is increases 1.25 % each sec
suppose B is the heart beat at first second therefore heat beat at 2 nd second
For 3 rd sec
similarly for 3 sec
