Question

Find sin A, cos A, tan A, and Sin B, cos B, and tan b in right triangle ABC, with c = 90 degree, if 1. a = 1 and b = 2. b = 3 and c = 6 a = 3 and c = 5 a = 5 and b = 12 Fill in the blanks to make each statement true. sin 14 degree - cos sec csc 73 degree simplify each expression as mu Ch as possible sin^2 45 degree + cos^2 30 degree tan 45 degree + cos 45 degree sin^2 60 degree - cos^2 30 degree 1/sec 30 degree Add 48 degree 18' and 24 degree 52. subtract 15 degree 32 from 25 15 convert to degrees and minutes 73.2 degree 16.45 degree convert to decimal degrees. 2 degree 48 79 degree 30 use a calculator to find the following 2 degree 48 79 degree 30 degree use a calculator to find the following sin 24 degree 20 degree cos 37.8 degree tan 63 degr5ee 50' cot 71 degree 20' use a calculator to find theta if theta is an acute angle and tan theta = 0.0816 sec theta = 1.923 sin theta = 0.9465 cos theta = 0.9730 Give the number of significant digits in each number. 49.35 0.0028 The following problems refer to right triangle ABC with C = 90 degree In each case, find all the missing parts. a = 68.0 and b = 104 a = 24.3 and c = 48.1 b = 305 and b = 24.9 c = 0.462 and a = 35 degree 30 If the altitude of an isosceles triangle is 25 cm and each of the two equal angles measures 17 degree how long are the two equal sides?

Explanation / Answer

sin260-cos230

(Sqrt3/2)2-(sqrt3/2)2=0

10.1/sec30=cos30 =sqrt3/2

11.48°18'+24°52' =72°70'=73°10'
