An electricity pole has a height of 6 m and a radius of 0.21 m.What is the total surface area of the pole? SpletGiven that sin (x + 10)º = cos (3x + 20)º, find the number of degrees in the acute angles of the corresponding right triangle. Choose: 30º and 60º 45º and 45º 25º and 65º 40º and 50º 10. In right ΔABC, m∠C = 90º and m∠A does not equal the m∠B. If sin A = m and cos A = k, find cos B + sin B. Choose: m + k m - k k - m 90 - (m + k)

SpletOT² = OQ² + TQ². Substituting in the known values, we get: OT² = 4² + x². Solving for OT gives: OT = sqrt (4² + x²) Now we need to find the value of x. To do this, we can use the fact that triangle OTQ is a 45-45-90 triangle. In a 45-45-90 triangle, the lengths of the sides are related by a ratio of 1 : 1 : sqrt (2). SpletIt's also useful for finding a missing side when given the other sides and one angle measure. Example 1: Finding an angle Let's find m\angle B m∠B in the following triangle: According to the law of cosines: (AC)^2= (AB)^2+ (BC)^2-2 (AB) (BC)\cos (\angle B) (AC)2 = (AB)2 + (B C)2 − 2(AB)(B C) cos(∠B) Now we can plug the values and solve: shooting compound bow from tree stand deer

Splet• A straight angle is an angle whose rays form a straight line, making ∠ABB'' a straight angle with a measure of 180º. Now, m∠ABC + m∠A'BB' + m∠B''BA' = 180. • Rotations preserve angle measure, making m∠A'BB' = m∠ACB and m∠BAC = m∠BA'C = m∠A'BB''. • By substitution, m∠ABC + m∠ACB + m∠BAC = 180. Traditional (Classical) Proofs: SpletABC with m∠A = 45°, m∠B = 30°, and BC = 14 Find: AB Draw altitude CD from C to AB.
