The measures of the angles of a triangle are shown in the figure below. Solve for x. Arrange the steps needed to solve for "x" in the correct order from the list provided below

FYI: Some of them will not be used.

x = 16

Step-by-step explanation:

( 2x + 18 ) + ( 4x + 11 ) + 55 = 180

6x + 29 + 55 = 180

6x + 84 = 180

180 - 84 = 96

6x = 96

96/6 = 16

6x/6 = x

x = 16

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
