QF Q8.) Solve the triangle.
Anuta_ua [19.1K]
A triangle solver tells you
  C = 85°
  b ≈ 8.4
  c ≈ 10.4

From the sum of angles of a triangle, 
  C = 180° -42° -53° = 85°

From the law of sines
  b = sin(53°)/sin(42°)*7 ≈ 8.355
  c = sin(85°)/sin(42°)*7 ≈ 10.422

Prove the sum of two rational numbers is rational where a, b, c, and d are integers and b and d cannot be zero.
uranmaximum [27]

Step-by-step explanation:

just look what happened :

every term was multiplied by a factor with the value 1 (to keep the original value) but to establish a common denominator.

a/b was multiplied by d/d, and c/d was multiplied by b/b, so that the common denominator is then bd.

so, the first answer option is correct.

although I am a bit unhappy with its phrasing.

but the other options are definitely wrong.
