Find the solutions for a triangle with a =16 c =12 and b=63 degrees

Side b is 15.02,

Angle C is 45.39° and angle A is 71.61°

Step-by-step explanation:

Let in triangle ABC,

BC = a = 16 unit,

AB = c = 12 unit,

∠B = 63°,

By the law of cosine,

By substituting the values,

By the law of sine,

∵ The sum of all interior angles of a triangle is supplementary,

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A + 63° + 45.39° = 180°

⇒ ∠ A + 108.39° = 180°

⇒ ∠A = 71.61°

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
