WebSep 5, 2024 · Solve the right triangle shown below. Use the approximations csc20 ∘ ≈ 2.92 and tan20 ∘ ≈ 0.364, and give the lengths to the nearest tenth. Answer Remember that the acute angles in a right triangle are complementary, which means their sum is 90 ∘. Since m∠A = 20 ∘, it follows that m∠B = 90 ∘ − 20 ∘ = 70 ∘. WebIn a right angled triangle, the side opposite the right angle is called the hypotenuse. If one of the other angles is \(x^\circ\) , then we can label the remaining sides as shown in this diagram ...
