Question

can anyone solve this​

Answer 1

Answer:

It is proved in the explanation section

Step-by-step explanation:

Since AE || BC and DAB is the transversal

$\angle DAE=\angle ABC=\angle B$

Since AE || BC and AC is the transversal

$\angle CAE=\angle ABC=\angle C$

But AE bisects $\angle CAE$

$\angle DAE=\angle CAE\\ \\ \angle B=\angle C$

AB = AC [Sides opposite to equal angles are equal]

Answer 2

Answer:

A ball is thrown from ground level. Three seconds later it is moving horizontally at 15 m/s. Find: (a) the horizontal range; (b) the angle of impact.
