Can you help me find the value of X?
Rashid [163]

Answer:

  x ≈ 4.1 cm

Step-by-step explanation:

The side (z) opposite the 42° triangle can be found from the relation ...

  z/(3.6 cm) = tan(42°)

  z = (3.6 cm)·tan(42°) ≈ 3.2415 cm

The relationship between z and x is ...

  z/x = cos(38°)

  x = z/cos(38°) ≈ 4.1135 cm

  x ≈ 4.1 cm

The sum of the interior angles of a convex n-sided polygon can be found using the formula:
Maksim231197 [3]

It is: 180(n-2)

For example, the sum of the interior angles of a triangle is 180 degrees.

The quadrilateral can be cut into two triangle so the sum of the interior angles of a quadrilateral is 180*2=180*(4-2)

The pentagon can be cut into three triangle so the sum of the interior angles of a pentagon is: 180*3=180*(5-2)

The hexagon  can be cut into four triangle so the sum of the interior angles of a hexagon is: 180*4=180*(6-2)

WINSTONCH [101]

Answer:

If your asking us to just combine like terms it would be -3b^2-2b^2+1.4b+4c+c

but if your asking us to answer the question it would be -5b^2+1.4b+5c

Hope I helped :)
