Question

in ∆abc a=90⁰ c = 60⁰ and ac= 19cm then ab=​

Answer 1

Step-by-step explanation:

the sum of angles of triangle is 180

so,

angle a+angle b+angle c=180

90+angle b+60=180

150+angle b=180

angle b=180-150

angle b=30

Answer 2

Answer:

You have to use Trigonometric Equations to get The Answer

Step-by-step explanation:

The answer is 19 root 3 or 19 × 1.73 = 32.87 cm

c is 60° so to find ab you can use tan c = ab/ ac = ab / 19

tan 60° is also equal to root 3 .

so ab / 19 = 1.73

ab = 32.87
