Answer:

38°

Step-by-step explanation:

The angles in a triangle always add up to 180 degrees.

Therefore, all the angles in the triangle given in the question add up to 180 degrees.

So, let's create an equation and solve for $x$ :

$x+44 + 63 + 85 + x = 180$

Simplify:

$2x + 192=180$

Solving for $x$ we get:

$2x=-12\\x=-6$

Now, let's put the value of $x$ we got into the formula for angle A.

$x+44=y$

$-6+44=y=38$

What is the value of X?

Leviafan [203]

Answer:

x=20

Step-by-step explanation:

First, find LJ

Angle L = 60 (180 - 30 - 90)

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(L)=adj/hyp

cos(60)=LJ/40√2

LJ = cos(60)*40√2

LJ = 20√2

Now you can use LJ to find x. You also know the value of each angle, 45

x=20√2⋅cos(45)

x=20

The width of a rectangle is 8 cm less than its length. The perimeter of the rectangle is 52 cm.What is the width of the rectangl

astraxan [27]

Let X be width of a rectangle, then
(x+8) - length

(x+x+8)*2 = 52
x+x+8 = 52/2
2x+8 = 26
2x = 26-8
2x = 18
x = 18/2
x = 9 cm

Answer: 9 cm.
