Determine the measures of angle ACB, angle DCE, & Angle BCD.

Mathematics
1 answer:
ruslelena [56]3 years ago
7 0

Answer: ∠ACB= 60°, ∠DCE= 65°, ∠BCD= 55°

Step-by-step explanation:

1) Since ΔABC is an equilateral, we know ∠ACB= 60°

2) Since we know ΔCDE is an isosceles, we know that ∠DCE= 1/2 (180-50), which is 65°

3) We can add the 2 angles and then subtract them from 180 degrees to get ∠BCD= 55°

To calculate the cost of painting his silo, a farmer must find its height. The farmer uses a cardboard square to line up the top
tankabanditka [31]

Answer:

Height of the silo = 18 feet.

Step-by-step explanation:

From the figure attached BC is the length of the silo and the height of the farmer is 5 ft.

Farmer is standing at 8 ft distance from the silo.

From triangle AEC,

tan(∠CAE) = \frac{CE}{AE}

                 = \frac{5}{8}

m(∠CAE) = tan^{-1}(\frac{5}{8})

               = 32°

m∠BAE = 90° - 32° = 58°

From the triangle ABE,

tan58° = \frac{BE}{AE}

BE = 8tan58°

BE = 12.8 ft

Total height of the silo = BE + EC

                                         = 12.8 + 5

                                         = 17.8

                                         ≈ 18 ft          

Therefore, total height of the silo is 18 ft.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
andre [41]

Answer:

Option A is correct.

Step-by-step explanation:

If Δ YES ∼ Δ NOT, then it means that ΔYES and ΔNOT are similar triangles.

The similar triangles means that all the corresponding angles of the two triangles are same i.e. ∠ Y = ∠ N, ∠ E = ∠ O and ∠ S = ∠ T

Therefore, according to the property of similar triangles we can write that

\frac{NO}{YE} = \frac{OT}{ES}  = \frac{NT}{YS}.

Therefore, option A is correct.
