Question

in triangle abc, angle b= 90°,AC = 10cm, bc= 6 cm find sin a and cos a​

Answer 1

Step-by-step explanation:

AC=10cm

BC=6cm

the points are on a straight line

so AB=AC-BC

AB=10–6

AB=4cm.

if ABC is a right angled triangle and AC is the hypotenuse

then using Pythagoras theorem AC^2=AB^2 +BC^2

therefore AB=8cm
