Answer:

A. Similar

Step-by-step explanation:

We are given the measurements of ΔQRS and ΔTUV as,

QR = RS = 4, QS = 2 with ∠Q = ∠S = 76°, ∠R = 28°

TU = UV = 12, TV = 6 with ∠T = ∠V = 76°, ∠U = 28°

Now, we see that,

These triangles have different side lengths. So, option C i.e. same sides is not correct.

Also, they are different in size. So, option D i.e. same size is not correct.

Since, they do not have same size, they cannot overlap each other. Thus, are not congruent. So, option B is also not correct.

Thus, we see that from SAS Similarity and the measurements,

QR = RS = 4 and ∠R = 28°

TU = UV = 12 and ∠U = 28°

<em>Both the triangles are similar to each other.</em>

Hence, option A is correct.

Answer:

(-2, 4)

Step-by-step explanation:

One of the equations is already solved for y, so let's solve the other one for y and by the transitive proprerty of equality, if y = y, then what those y's are equal to are equal to each other. Solving the first equation for y:

x + y = 2 so

y = -x + 2

Let's fill that in for y in the second equation. Where

$y=\frac{1}{2}x+5$ , making the substitution,

$-x+2=\frac{1}{2}x+5$

Combining like terms and getting the x on one side and the constant on the other side of the equals sign:

$-\frac{3}{2}x=3$

The product of a fraction and its reciprocal is 1 so we will multiply both sides by

$-\frac{2}{3}$ to get:

$(-\frac{2}{3})(-\frac{3}{2})x=(3)(-\frac{2}{3})$

and we end up with x = -2.

Now that we know that, we can sub that in for x in either one of the original equations. I chose the first one:

If x + y = 2, then -2 + y = 2

and y = 4

Therefore, the solution set is (-2, 4)

The figure below shows a shaded circular region inside a larger circle:

myrzilka [38]

Probability that the point chosen is not inside the shaded area is given as follows:
Probability=(area of unshaded part)/(area of the large circle)
Area of unshaded part will be:
A=(area of large circle)-(area of small circle)
area of large circle=πR²=π×5²=25π in²
area of small circle=πr²=π×3²=9π

Area of un-shaded part=25π-9π=16π in²
thus the probability that part chosen is not shaded will be:
16π/25π
=0.64
=64%

Answer: 64%
