Find the m∠YAX in the figure below

11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

The two angles are vertical angles so they are equal

3x+7 = 4x-16

Subtract 3x from each side

3x-3x+7 = 4x-3x-16

7 = x-16

Add 16 to each side

7+16 = x-16+16

23 =x

We want YAX

YAX = 3x+7

3*23+7

69+7

Find the area of the figure. Round to the nearest tenth if necessary.

4vir4ik [10]

Answer:

$A=782\ yd^2$

Step-by-step explanation:

The area of the figure is equal to the area of four right triangles

The area of one right triangle is equal to

$A=\frac{1}{2}(23)(17)$

$A=195.5\ yd^2$

Multiply by 4

$A=(4)195.5=782\ yd^2$

<em>Alternative Method</em>

The figure is a Rhombus

The area of the Rhombus is equal to

$A=\frac{1}{2}(D_1)(D_2)$

where

D1 and D2 are the diagonals of the rhombus

we have

$D_1=(23+23)=46\ yd\\D_2=(17+17)=34\ yd$

substitute

$A=\frac{1}{2}(46)(34)$

$A=782\ yd^2$
