Question

if triangle ABC is a right triangle,such that angle c=90 degree,angle A =45 degree & BC =7 units.Find angle B,AB & AC

Answer 1

we know that
angle a+b+c=180°

90°+45°+b=180°
b= 45°


given. BC =7
/_b = 45°


now tan 45° =1

in triangle abc

1=AC/7
ac =7


now sin45° =1/√2

in triangle abc

1/√2= 7/ab

ab= 7√2 meter



hence b =45° ab= 7√2 unit

ac=7 units
