WebJul 31, 2024 · Given triangle ABC, which equation could be used to find the measure of ∠C? PLEASE HELP URGENT right triangle ABC with AB measuring 6, AC measuring 3, and BC … WebSubstituting the right side of this equation for ∠ B in our inequality we get: 180 ° – ∠ A – ∠ C > 90 °. We know that ∠ A = 25 °, so let’s plug that in now: 180 ° – 25 ° – ∠ C > 90. Now let’s simplify this and solve for ∠ C, remembering that we need to switch the direction of inequality symbols whenever we multiply ...
WebAnswer (1 of 2): Length of the median through A: \frac{3\sqrt{2}}{2} Solution: We are given the lengths of two sides of a triangle and we can calculate length of the third side. Lengths of sides of triangle are: AB =\sqrt{2} \approx 1.414 AC = \sqrt{20} \approx 4.4721 BC = \sqrt{(3-0)^2 + (2...
