A key word to remember when doing this type of math is "SOHCAHTOA".

Sine =

Opposite over

Hypotenuse

Cosine =

Adjacent over

Hypotenuse

Tangent =

Opposite over

Adjacent

Since this is a 3, 4, 5 triangle, with the sides just multiplied by 7, the opposite of A which is 28 would be simplified to 4.

And the Hypotenuse would be simplified to 5.

So, the answer is 4 / 5!

Find A, given that a = 18.2, B=62°, and C= 48°. Round to the nearest whole degree.

fomenos

Answer:

Step-by-step explanation:

If we are given angles B and C, then all we have to do is add them together and then subtract that from 180 since all the angles of a triangle have to add up to equal 180.

62 + 48 = 110

180 - 110 = 70

Angle A = 70°
