Web15 jun. 2024 · List the sides in order, from shortest to longest. Figure 4.25.8 Solution First, find m\angle A. From the Triangle Sum Theorem: m∠A + 86 ∘ + 27 ∘ = 180 ∘ m∠A = 67 ∘ 86 ∘ is the largest angle, so AC is the longest side. The next angle is 67 ∘, so BC would be the next longest side. 27 ∘ is the smallest angle, so AB is the shortest side. WebIf a triangle has sides a,b,c then all of the following conditions must be true a b+c b a+c c a+b Any two sides must add to be larger than the third side. See the triangle inequality theorem. In option 1, we have: a = 4, b = 4, c = 8 And a+b = 4+4 = 8 which does not exceed c = 8 In other words, c a+b is not true. A triangle isn't possible here.

If a triangle has two angles congruent, then two sides are congruent
Web15 jun. 2024 · 30 degrees + 45 degrees = 75 degrees. Find the measure of angle C by subtracting the total of the two measurements from 180 degrees to find the measure of the third angle. 180 - 75 = 105. Angle C = 105 degrees. Add the answer and the two supplied angle measurements to check for accuracy. The sum of all three angles should equal … Web18 nov. 2024 · 1. Given two sides. If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem: a² + b² = c². If leg a … WebExample 3. The diagonal of a right triangle is 8 cm. Find the lengths of the other two sides of the triangle given that one of its angles is 30 degrees. Solution. This is must be a 30°-60°-90° triangle. Therefore, we use the ratio of x: x√3:2x. Diagonal = hypotenuse = 8cm. ⇒2x = 8 cm. ⇒ x = 4cm. Substitute. phos electrolyte repletion
