Answer + ! what is the length of side c, given a = 10, b = 8, and c = 105°? round the answer to the nearest tenth. [not drawn to scale] a. 2.3 b. 8.8 c. 11.1 d. 14.3

Using the law of Cosines:

c^2 = 10^2 + 8^2 - 2*10*8*cos(105)

c^2 = 205.41
c = SQRT(205.41)
c = 14.3
 The answer is D

The 3rd quadrant as 3x+g5ti=56i: 92d-543

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
