Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate. a = 7.3 in.
b = 13.2 in.
c = 15.8 in.

A = 27.3°, B = 56.1°, C = 96.6°
No triangle satisfies the given conditions.
A = 29.3°, B = 54.1°, C = 96.6°
A = 25.3°, B = 56.1°, C = 98.6°

Use the Law of Cosines to find the measure of angle A from the lengths of the sides.

A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°

B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°

C = 180 - A - B = 95.3°

10/12 + 2/12 = 12/12 or 1 whole

Step-by-step explanation: Since it says at first the dino ate 10/12 and then after it ate 2/12 more. When your adding fractions the denominator doesn't change but the numerator does. Therefore its basically saying what's 10+2 which = 12 then you put the denominator on the bottom which is 12/12 if you want to simplify it. It turns to a 1 whole
