Answer:

∠DSE = 24°

Step-by-step explanation:

The ∠ASE = 168° is the sum of the angles

∠ASB + ∠BSC + ∠CSD + ∠DSE, thus

13° + 85° + 46° +∠DSE = 168°, that is

144° + ∠DSE = 168° ( subtract 144° from both sides )

∠DSE = 24°

A rectangle has an area of 72 swaure units. The width of the rectangle is 9 units. The length of the rectangle is 2x + 4. What i

vichka [17]

Answer:

8 units

Step-by-step explanation:

Area of a rectangle = Width multiplied by Length

Substitute in all the known numbers into this formula to get

72 = (9) × $(2x+4)$

Solve the equation for x, to find out the length

$9(2x+4)=72$

$2x+4=72/9$

$2x+4=8$

$2x=8-4$

$2x=4$

$x=4/2$

$x=2$

Length of the rectangle = $(2x+4)$

$2(2)+4$

$4+4=8$
