Question

In ΔABC, ∠B = 90o
, AB = 6 cm and AC = 12 cm. Find ∠A and ∠C.

Answer 1

Answer:

we know that ABC is the right angle triangle,

so,

AC×AC= AB×AB×BC×BC

12×12=6×6×BC×BC

144=36×BC×BC

BC×BC=144÷36

BC×BC=4

BC=2

Now,

We know that,

angle A+angel B+angel C=180°

angle A+90°+angle C= 180
