WebLook at the 37 degree. The side across from it, or the opposite, is what you are trying to find so it will be your x or unknown value. You know the adjacent side, it is three. So you will set up your equation like this tan (37)=x/3 The 37 comes from the degree you used as a reference point. WebNov 16, 2014 · The triangle is completely determined by its side lengths A B ¯, A C ¯, B C ¯, which you say are all known (the knowledge of h and A B C being isosceles is unnecessary). Let D be the point where the altitude touches segment BC. Then A D A B = cos θ, or θ = Angle BAD = arccos ( A D A B). The same logic apples to angle CAD= arccos ( A D A C).

WebMath. Precalculus. Precalculus questions and answers. In triangle ABC, AC = 12, the measure of angle A = 30 degree, and the measure of angle B = 45 degree. Find the area of this triangle. 18 Squareroot 3 54 Squareroot 3 18 (1 + Squareroot 3) 54 (1 + Squareroot 3) 12 (1 + Squareroot 3) None of the above. WebSep 22, 2024 · This is the angle outside the triangle because the direction B C → is pointing relative to A B →, and so, we should find the supplementary angle that is: β = 180 ∘ − 126.5 ∘ = 53.5 ∘ Let γ be the angle between A C → and B C →. Since the sum of the angles of a triangle is 180 ∘, so: α + β + γ = 180 ∘ 97.67 ∘ + 53.5 ∘ + γ = 180 ∘ 151.17 ∘ + γ = 180 ∘ WebQuestion 469051: To the nearest degree, find the measure of angle B in Triangle ABC given measure of Angle A=31 degrees, AC=36 and AB=35 Answer by ccs2011(207) (Show Source): You can put this solution on YOUR website!
