Mathematics
1 answer:
Nostrana [21]2 years ago

Answer:

Below in bold

Step-by-step explanation:

I AM ASSUMING that CDEF is a Rhombus.

If it is than triangle DEG is right-angled.

so 2x + 18 + 5x + 2 = 90.

7x = 90 - 20 = 70

x = 7.

So m < CDF  = 5x + 2

= 5(10) + 2

= 52 degrees.

m < DCE = 2(10) + 18 = 38 degrees.

The diagonal bisects < DCF so m < ECF = 38 degrees.

So m < DCF = 2 * 38 = 76 degrees.

Opposite angles of a rhombus are equal so m < DEF = 76 degrees.

tankabanditka [31]

Answer:

x = 100√3


Step-by-step explanation:

tan(30º) = x/300

x = 300 tan(30º)

x = 300/√3

PLEASE HELP ME.Math work: The Head Chef has asked you to create a delicious baked dessert that will have the same volume if it i
nikklg [1K]

Answer:

Large baking dish of cylinder, cone and sphere.

Step-by-step explanation:

When we compute the volume of each of the small and large baking dish taking \pi=3.14, we get

Volume of cylinder (small dish)= \pi(r^2)(h)

                                                  =3.14(\frac{3}{2})^2*3

                                                  = \frac{3.14*9*3}{4}

                                                 = 21.195

Volume of cylinder (large dish)= \pi(r)^2(h)= 3.14*(3)^2(3)

                                                  =84.78

Similarly, volume of cone (smaller dish)= \frac{1}{3} \pi r^{2} h

                                                            = 7.065

Volume of cone (larger dish)= 84.78

Volume of sphere(smaller dish)= \frac{4}{3} \pi r^{3}

                                                    = 14.13

Volume of sphere (larger dish) = 85.17 (approx)

Hence, we get that larger baking dish have approximately same volume.

Therefore, large baking dish of cylinder, cone, sphere will be chosen.
