The first plane flies to a landing strip 350 miles south, while the other plane flies to an airport 725 miles west. To the nearest hundredth, how far apart are the two planes after they land? 2. An escalator in a shopping mall is 40 ft long and 32 ft tall. To the nearest hundredth, what distance does the escalator carry shoppers? 725 350² + 725² = c² 648125 = c² 350 805.06 = c 32² + 40² = c² 2,624 = c² C 32 ft 51.22 = c 40 ft

Angles When the sides of a polygon are extended, other angles are formed. The original angles are the interior angles. The angles that form linear pairs with the interior angles are the exterior angles.

Exterior Angle Theorem An exterior angle of a triangle… … is equal in measure to the sum of the measures of its two remote interior angles. remote interior angles Exterior angle

Exterior Angle Theorem (your new best friend) The measure of an exterior angle in a triangle is the sum of the measures of the 2 remote interior angles exterior angle remote interior angles 3 2 1 4 m<1 + m<2 = m<4

Exterior Angle Theorem m∠1 = m∠A + m∠B

Examples m<G = 111 - 60

x = 68° y = 112° Examples Find x & y y = 30 + 82 y = 112˚ 82° 30° x y
