The diagram below shows a 30 degrees-60 degrees -90 degrees triangle. a. Find the lengths of the missing sides. Show how to find the lengths. b. Find the sine, cosine, and tangent of 30 degrees. Write as decimals rounded to four decimal places. c. Find the sine, cosine, and tangent of 60 degrees. Write as decimals rounded to four decimal places. d. Describe any relationships between the trigonometric ratios for 30 degrees and the trigonometric ratios for 60 degrees.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5

step-by-step explanation:

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading

step-by-step explanation:

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
