That is a isosceles triangle, therefore x and the top angle are the same.

There’s 180 degrees in a triangle.

Therefore:

(180 - 38)/2 = x
142/2 = x
71 = x

Answer:

X=71 degrees

Step-by-step explanation:

Because it's an isosceles triangle, the length of two side should be same. Which means two of the angle should also be the same. Therefore, with that information we can get

2x+38=180

Move 38 to the other side

2x=142

Move "2" to another side by divide both side by 2

x=71

Now you get the answer.

If two of the four expressions x + y, x + 5y, x – y, and 5x – y are chosen at random, what is the probability that their product

storchak [24]

Answer:

1/6

Step-by-step explanation:

The product will only be of the required form if the two chosen factors are of the form (x +by) and (x -by).

For the factor (x+y), there is also a factor (x-y) on the list. For the factor (x+5y), there is no factor (x-5y) available.

So, of the (4·3)/2 = 6 possible ways to choose two expressions from the four given expressions, only one pair of the 6 will have a product of the required form.

The probability is 1/6.

If A=p+prt, than t equalls?

ella [17]

Answer:

$\boxed{t=\frac{A-p}{pr}}$

Step-by-step explanation:

$A=p+prt$

Subtract p on both sides.

$A-p=p+prt-p$

$A-p=prt$

Divide both sides by pr.

$\displaystyle \frac{A-p}{pr} =\frac{prt}{pr}$

$\displaystyle{\frac{A-p}{pr} =t}$

Please help me with this geometry question, Im pretty sure you need to use SAS congruence rule

Ierofanga [76]

Congruent triangles are two or more triangles with the same length of sides and measure of internal angles. Thus the required proof is as shown below:

From the given diagram, it can be observed that:

AB = AC (similar property of two lines)

AC = AE (similar property of two lines)

Also,

m<A is a common angle to ΔABC and ΔADE

So that it can be concluded that;

ΔABC ≅ ΔADE (Side-Angle-Side property)

Thus since ΔABC ≅ ΔADE are congruent, then;

BC = DE (corresponding sides of congruent triangles)
