How would you solve for x and y?

Mathematics
1 answer:
Sholpan [36]3 years ago
4 0
Since all of the sides are 15, and there's a right angle, we can assume the triangles are both the same size. So we can halve 15 to get the length of y, which would be 7.5. And here we can use the Pythagorean's Theorem to solve for x, by changing it to c^2-b^2=a^2, and we can fill out 15^2 - 7.5^2 = a^2, or 225 - 56.25 = √173.75, which is about 13.18.

Find MP.<br><br> MN=17<br> NP=3y<br> MP=5y+9
8_murik_8 [283]

Answer:

MP = 29

Step-by-step explanation:

Given:

MN = 17

NP = 3y

MP = 5y + 9

MN + NP = MP (segment addition postulate)

17 + 3y = 5y + 9 (substitution)

3y = 5y + 9 - 17 (subtracting 17 from each side)

3y = 5y + 8

3y - 5y = 5y - 8 - 5y (Subtracting 5y from both sides)

-2y = 5y - 8 - 5y

-2y = - 8

y = 4 (dividing both sides by -2)

MP = 5y + 9

Plug in the value of y

MP = 5(4) + 9 = 20 + 9

MP = 29

Please help! Brainliest Answer! Thank You!

Answer:

B) 63°

Step-by-step explanation:

<u>Step 1:</u> find the angle beside x (inside the pentagon)

<em>*A pentagon has a total of 540°</em>

119 + 100 + 116 + 88 = 423

540 - 423 = 117

<u>Step 2:</u> x is a supplementary angle, which means it's angle adds up to 180°

Since we know the other angle is 117°, we just subtract that from 180

180 - 117 = 63

x = 63

A party rental company has chairs and tables for rent. The total cost to rent
Paha777 [63]

Let c= cost to rent each other

Let t= cost to rent each other

2c+3t=25

6T+5T=49

Multiply the 2nd equation by (-2) and add equation together  

2c+3t=25

-12c-10t= 98

2t=98

T=49

Put this value into the 1st equation solve c

2c+3(49)=49

2c+147=49

2c=98

C=49

Cost to each chair and table are same 49.
