Answer:

4.891

its side b (opposite side of the 50 degree angle)

Step-by-step explanation:

side c = 6

angle A is 20 side a (opposite side) = 2.184

angle B is 50 side b (opposite side) = 4.891

angle C is 110 side c (opposite side) = 6

1.

get third angle

50 + 20 = 70

180 - 70 = 110

third angle C is 110

2.

get side a

sin A/a = sin C/c

a/c = sinA/sinC

a = c * sinA/sinC

a = 6 * (sin20/sin110)

get sin in degrees

a = 6 * (.342/.9397)

a = 2.184

The drawing of the triangle is as shown below.

The length x in the drawing is 4.9 cm

What is triangle?

  • "It is a two-dimensional shape with three sides, three angles, and three vertices."
  • "The sum of all angles of triangle is 180° "

For given question,

To draw required triangle,

- First make a horizontal line segment of 6 cm using ruler.

- Then place the protector on the left vertex of the segment, make angle of 50° and draw the arm of angle.

- Then place the protector on the right vertex of the segment, make angle of 20° and draw the arm of angle.

- The intersection point of both the arms would complete the required triangle.

- Measure the length x in the drawing using ruler.

The drawing of the triangle is as shown below.

The length x in the drawing is 4.9 cm
