Answer:
x = 14.5
Explanation:
Given
A = 19
B = ?
C = ? , C = 45°
a. To find the other two angles of the triangle subtract 45° from 180° .
180° - 45°
135
b. Divide 135 by 2 to get the two sides.
135°÷2 = 67.5°
So the other two angles are 67.5° and 67.5°.
To check your answer 45°+ 67.5° +67.5° = 180°
c. a/sinA = c/sinC
c sin67.5°/sin67.5° = 19 sin45°/sin67.5°
c = 14.5
Therefore x = 14.5
