Suppose that ∠BNR and ∠RNA are adjacent angles where m∠BNR=12w-19,

wariber [46]

Answer:

Step-by-step explanation:

Sum of interior adjacent angle is 180 degrees.

Given

m∠BNR=12w-19,

m∠RNA= ¼(w+199)

m∠BNA=2(12w-19).

Substitute

m∠BNR+m∠RNA=

¼(w+199)+12w-19, = 2(12w-19).

W+796+48W-76 = 96W-152

49W-96W = -152+76-796

-47W = 872

W = 872/47

W = 18.55

Ivenika [448]

Answer:

Step-by-step explanation:

39 feet for one side

40 feet for another

42 feet for the last side

I got the answer by adding 1 foot to the first side which comes out to be 40 feet, I got the last answer by adding 2 feet to 40 which is 42.

Given that ABCD is a rhombus, find the value of x.<br> (X+14)

Kay [80]

Answer:

option B. $x=38^o$

Step-by-step explanation:

we know that

1) The two diagonals of a rhombus are perpendicular

2) The sum of the interior angles in any triangle must be equal to 180 degrees

Let

O ----> the intersection point of the diagonals of the rhombus

In the right triangle OAD

$x^o+(x+14)^o+90^o=180^o$

solve for x

$x^o+(x+14)^o=90^o$

$2x=90^o-14^o$

$2x=76^o$

$x=38^o$
