Solve for X and solve for Y?

Mathematics
1 answer:
Llana [10]3 years ago
7 0

Answer:

x=3\sqrt 5\\

y = \sqrt {126}

Step-by-step explanation:

By geometric mean property:

x =  \sqrt{9 \times 5}  =  \sqrt{45} = 3 \sqrt{5}   \\  \\ by \: pythagoras \: theorem \\  \\  {y}^{2}  =  {9}^{2}  +  {x}^{2}  \\  \\  {y}^{2}  =  {9}^{2}  +  {(3 \sqrt{5}) }^{2}  \\  \\  {y}^{2}  = 81 + 45 \\  \\  {y}^{2}  = 126 \\  \\ y =  \sqrt{126}

Plz help me well mark brainliest if correct!....
LUCKY_DIMON [66]

Answer:

C

Step-by-step explanation:

B can immediately be eliminated because it has an area of 14.

A and C have an area of 10.

So add the sides.

C:

4 + 4 + 1 + 1 + 2 + 2 + 1 + 3

= 18

A: 3 + 3 + 2 + 2 + 1 + 1 + 1 + 1 =

10 + 4 =

14

Will adding a negative number to another integer always result in a negative sum? Why?
Ghella [55]

Answer:

  D  No, the integer with the larger absolute value always determines the sign of the sum.

Step-by-step explanation:

Suppose the integer you start with is +3. Adding -1 or -2 or -3 to that will result in 2, 1, or 0, none of which are negative. Only when you add a negative number with an absolute value greater than 3 will you get a sum that is negative. That is, <em>the number in the sum that has the largest absolute value determines the sign of the result</em>. (This is most important when the signs differ, but it is also true when the signs are the same.)

CONGRUENT TRIANGLES WORKSHEET. NEED ASAP DUE TODAY
WINSTONCH [101]

Answer:

Congurent triangles are those which map onto them selves perfectly. This means they share the same angle measurements and side lengths. Therefor we can figure out the side lengths by using the information in both triangles.

AD=5x+11

in the congurent triangle, the corresponding side equals:

CM=7x-3

CM and AD are congurent triangles meaning their sidelengths equal the same. Therefore...

5x+11=7x-3

Now we just solve to find the length of AD and CM (equal lengths)

5x+11=7x-3

11=2x-3

14=2x

7=x

x=7

If x=7 then we can plug it in for AD to find the side length.

5(7)+11=46

Notice that CM equals the same 7(7)-3=46

This is because... they are congruent triangles.

These rules also apply for all angle measurements of congruent triangles:

The m<v is equal to the meaasure of E (corresponding angles in congrurent triangles are equal)

We already astablished what x was (x=7) meaning if we find the measure of E then we have the measure of V sicne they are corresponding angles in a congrurent triangle.

(6x7+1)=43°

therefore the m<v is equal to 43°

46 and 43° is your answer
