Δabc is a right triangle in which angle b is a right angle, ab = 1, ac = 2, and bc = square root of 3 . cos c × sin a equals what

Remark

Study the triangle carefully. It may not be exactly as you have drawn it, but it will work if you just follow the givens.

AC = 2

AB = 1

BC = sqrt(3)

Step One

Find Cos C

Cos(C) = adjacent / Hypotenuse

Cos(C) = BC / AB

Cos(C) = sqrt(3)/2

Step Two

Find Sin(A)

Sin(A) = opposite / hypotenuse

Sin(A) = AB / AC

Sin(A) = 1/2

Step Three

Find Cos(C) * Sin(A)

Cos(C) * Sin(A) = sqrt(3)/2 * 1/2 = sqrt(3) / 4 <<<< Answer

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
