In the Equilateral triangle space all 3 sides have the same size /congruent every the three inner angles are also comparable in an equilateral triangle just the collection of equilateral triangles includes members that space always similar to one another because every the angles space fixed and also equal that is 60 degrees.Rest(trapezoids, isosceles triangles,rectangles, pentagons) walk not have actually fixed angle in it.

You are watching: Which set of shapes contains members that are always similar to one another?

Side BC = sqrt 80 or 8.94

Angle A = 48.19 degrees

Angle C = 41.81

Step-by-step explanation:

Using the Pythagorean Theorem, we have the right to solve because that the absent side, BC:

a^2 + b^2 = c^2 (Substitute)

8^2 + b^2 = 12^2 (Simplify)

64 + b^2 = 144 (Subtract 64 from both sides)

b^2 = 80

b = sqrt (80)

b is about equal to 9 and also when rounded to the hundredths, the is equal to 8.94.

Now that we know the sides, we deserve to use trig relationships in between the political parties to find the angles:

sin A = (sqrt 80)/12 (Using the square root straight will result in specific invernessgangshow.nets | take it the inverse sine the both sides)

A = sin-1 ((sqrt 80)/12)

Angle A = 48.19 degrees (approximation to the nearest hundredth)

We know that B is a right angle, thus 90 degrees.

sin C = 8/12 (Take the station sine of both sides)

C = sin-1 (8/12)

Angle C = 41.81 degrees (approximation to the nearest hundredth)

13. I beg your pardon equation represents the line below? <84>

y = -2/3x + 3

Step-by-step explanation:

First, we must calculate the slope of the line. We can do this by making use of the slope formula using two points:

(y₂ - y₁) / (x₂ - x₁)

If us take the clues (-3,5) and also (3,1), then: y₂ = 1; y₁ = 5; x₂ = 3; x₁ = -3

Next, we have the right to substitute in values in the equation above to get (1 -5)/(3+3)

** We got 3+3 because it was 3 - (-3), where 2 negatives same a positive**

Then, we get, -4/6, i beg your pardon simplifies come -2/3. Our steep is -2/3

After that, we require to discover the y-intercept, i beg your pardon is whereby the line intercepts the y-axis. Here, that is in ~ (0,3).

Therefore, if we put the above information right into slope-intercept form:

y = mx + b --> m = -2/3; b = 3

y = -2/3x + 3

Though ns don"t think the choice is there...
