Find the value of x rounded to the nearest degree

b 44 degrees

Step-by-step explanation:

cos x = adjacent side / hypotenuse

cos x = 15/21

cos x = 5/7

Take the inverse cos of each side

cos ^-1 (cos (x) )= cos ^-1 (5/7)

x =44.4153086

To the nearest degree

x = 44 degrees

The correct answer is option(b).  44°

Step-by-step explanation:

From the figure we can see a right angled triangle with one angle is x° and two sides are given.

To find the value of x

From the given figure we get the adjacent side of angle is given

Therefore we can write,

Cos x = Adjacent side/Hypotenuse

 = 15/21

 = 0.7142

x = Cos ⁻¹ (0.7142)

 = 44°

Therefore the value of x = 44°

The correct answer is option(b).  44°

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
