Answer:

x ≈ 23.6°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx° = \frac{opposite}{hypotenuse} = \frac{2}{5} , thus

x = sin^{-1} (\frac{2}{5} ) ≈ 23.6° ( to the nearest tenth )

Since we have the opposite and the hypotenuse, we have to use Sine so:

SinA = opposite/hypotenuse
Sin x = 2/5
Sin x = 0.4
x = sin inverse (0.4)
x = 23.57817848
Or if you want want to shorten it then
x = 23.57

Hope this helps!

Solve the following equation for x.<br> (3/5)x - 15 = (6/5)x + 12<br> 5<br> -5<br> -45<br> 45
Free_Kalibri [48]

Answer:

x = -45

Step-by-step explanation:

(3/5)x - 15 = (6/5)x + 12

(6/5)x - (3/5)x = -15 - 12

(3/5)x = -27

0.6x = -27

x = (-27)/0.6

x = -45

a rectangular ponds refectuons in a part is 16 feet long. The maintenance crew placed a string of flags 20 feet long across the
frosja888 [35]

Answer:

width = 12 ft

Step-by-step explanation:

Given the figure of the pond and the fact that the corners form a right triangle that is across from the string of flags, you can use the Pythagorean Theorem to solve for the width of the triangle that is formed by the flags:

a² + b² = c², where 'a' and 'b' represent the legs of the triangle and 'c' represents the diagonal or hypotenuse.  Using 16 for 'a' and 20 for 'c':

16² + b² = 20²

256 + b² = 400

Subtract 256 from both sides: 256 - 256 + b² = 400 - 256 or b² = 144

Take the square root of both sides:  √b² = √144  or b = 12 ft

Answer:the square footage of the parallelogram is 299 square feet.

Step-by-step explanation:

The formula for determining the area of a parallelogram is expressed as

Area of parallelogram = length × perpendicular height.

From the digram shown,

Length of the parallelogram is 23 feet.

perpendicular height of the parallelogram is 13 feet

Area of parallelogram = 23 × 13 = 299 square feet.
