In △ABC, m∠A=27 °, c=14 , and m∠B=25 °. Find a to the nearest tenth.
Gnesinka [82]

Answer:

a = 8.1

Step-by-step explanation:

Firstly, since we have a triangle, automatically, we have 3 interior angles

Mathematically the sum of these angles = 180

A + B + C = 180

27 + 25 + C = 180

52 + C = 180

C = 180-52

C = 128

We use the sine rule to find a

The sine rule posits that the ratio of a side to the sine of the angle facing that side is equal for all the sides of a triangle

Thus, mathematically according to the sine rule;

c/Sin C = a/Sin A

14/sin 128 = a/sin 27

a = 14sin27/sin 128 = 8.0657

which to the nearest tenth is 8.1

The midpoint of a line segment is (-1, 4). The endpoints of the line segment are (3, y) and (-5, 10). What is the value of y?
viktelen [127]

Answer:

  -2

Step-by-step explanation:

The midpoint is the average of the end point coordinates, so ...

  4 = (y +10)/2 . . . . the y-coordinate is the average of the y-coordinates

  8 = y +10 . . . . . . . multiply by 2

  -2 = y . . . . . . . . . . subtract 10
