Answer:

17°

Step-by-step explanation:

ΔXWZ = ΔYWZ  (they are congruent triangles so ∠XWZ = ∠YWZ)

5x - 8 = 9x - 28

Rearrange and collect the like terms

-8 + 28 = 9x - 5x

20 = 4x

x = 5°

∠YWZ = 9x - 28

sub x = 5

= 45 - 28

= 17°

Answer:

A     32.1

Step-by-step explanation:

Given two points (x_{1} ,y_{1} ) and (x_{2} ,y_{2}))

distance between to points = d = \sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} )^{2} }

Now B is (-4,5) and A is (2,0)

So AB = \sqrt{(-4-2)^{2} +(5-0)^{2} }  = \sqrt{36 + 25} = \sqrt{61\\} = 7.810...

C is (4,10)

So BC = \sqrt{(-4-4)^{2} +(5-10)^{2} } =\sqrt{64 + 25) } =\sqrt{89} =9.433...

D is (8,7)

So CD = \sqrt{(4-8)^{2} +(10-7)^{2} } =\sqrt{16 + 9} = \sqrt{25} = 5

E is (4,5)

So DE = \sqrt{(8-4)^{2} + (7-5)^{2} }  = \sqrt{16 + 4}  = \sqrt{20}  =  4.472...

and AE = \sqrt{(4-2)^2 + (5-0)^2} =\sqrt{4+25}  = \sqrt{29} = 5.385...

Perimeter = 7.810 + 9.433 + 5 + 4.472 + 5.385 = 32.1

Step-by-step explanation:

The total number of Major League Baseball teams is 30.

During a 10-year period, 6 out of 30 Major League Baseball teams won the World Series.

Therefore, the percentage of Major League Baseball teams won the World Series during the 10-year period would be

6/30 × 100 = 0.2 × 100 = 20%
