Find x in DEF<br><br>A. 6<br>B. 6 (square root 2)<br>C. 6 (square root 3)<br>D. 12​
netineya [11]

Answer:

B. 6√2

Step-by-step explanation:

We can use the Pythagorean Theorem to solve this out. The Pythagorean Theorem states that for any right triangle with the shortest sides (called legs) as a and b and the longest side (called the hypotenuse) as c:

a² + b² = c²

Here, a = b = 6, so:

6² + 6² = c²

36 + 36 = c²

72 = c²

c = √72 = 6√2

Now, we see the answer is B.

However, there's a trick to solving these kinds of problems. Notice that DEF is both an isosceles triangle and a right triangle. We call these 45-45-90 triangles because those are the angles of the triangle.

One characteristic of these types of triangles is that their leg to leg to hypotenuse ratio is 1 : 1 : √2, always. We could apply that here. We see that the legs are 6, so we could find the hypotenuse simply by multiplying 6 by √2, and we would get 6√2, which is exactly the value we obtained above.

Thus, the answer is B.

Suppose that E and F are two events and that Upper P left parenthesis Upper E and Upper F right parenthesisequals0.1 and Upper P
strojnjashka [21]

Answer:

P(F/E) = 0.5

Step-by-step explanation:

We have the following information:

P(E∩F)=0.1

P(E)=0.2

Additionally, the probability P(A/B) of event A given Event B is calculated as:

P(A/B) = P(A∩B)/P(B)

Now, we want the probability P(F/E), so it is calculated as:

P(F/E) = P(E∩F)/P(E)

Finally, replacing the values we get:

P(F/E) = 0.1 / 0.2

P(F/E) = 0.5

3. Evaluate a + b for a = -46 and b= 34.<br> A:-12<br> B:80<br> C:-80<br> D:12
blsea [12.9K]

Answer:

<h2>A: -12</h2>

Step-by-step explanation:

Put the values of a = -46 and b = 34 to the expression a + b:

-46 + 34        <em>use the commutative property a + b = b + a</em>

= 34 + (-46) = 34 - 46 = -12

Need help on the last ones
OlgaM077 [116]

the diagonals of a rhombus bisect the angles.

if angle 2 is 48, angle 4 is also 48. therefore, by alternating interior angles, angles 9 and 7 are also 48. This means m<MOH = 96.

if angle 7 is 61, angle 9 is 61 as well. this means m<MOH is 122. therefore m<RHO = 180 - m<MOH. this means m<RHO = 58.

I'm not sure I understand the context of 5. how are do they expect you to solve for x? you could solve for it in terms of m<3, which would mean x = (m<3 + 6)/8.
