Unit 1 Test: Triangle Similarity Flashcards Quizlet
WebIn triangle ABC, if angle A = 70 degrees, angle B = 40 degrees, and side AB = 8, what is the length of side BC? Answer: 6.25 (rounded to the nearest hundredth) A cylinder has a height of 10 units and a radius of 4 units. WebTo calculate the missing length of a triangle having 2 known sides and an included angle, you can use this formula c² = a² +b² - 2ab•cos C. In this case AC is b opposite ∠B, BC is a opposite ∠A, AB is c opposite ∠C in triangle ABC. b=7 cm and a=3 cm given, ∠C is variable since you want to make three non-congruent triangles. duping cheat
