For 6-7 In ∆FUN, F =65°, O = 75°, what is the shortest and the longest side? ____,____ For 8-10 In ∆DAY, DA = 12, DY = 20, AY = 10, give the angles from smallest to largest. opposite the larger side. ___,____,____,

Sagot :

Answer:

Alright, let's tackle these questions one by one.

For 6-7, in triangle FUN, we know that the angle measures add up to 180°, so the third angle, U, must be 40° (180° - 65° - 75°). Now, we know that the side opposite the largest angle is the largest side, so the longest side is the one opposite angle O, which is 75°.

For the shortest side, we can use the Law of Cosines:

a^2 = b^2 + c^2 - 2bc cos A
