What is the value of x?

Mathematics
1 answer:
torisob [31]3 years ago
3 0

Answer:

x=45^{o}

Step by step explanation:

We have been given that measure of angle A is fifty five degrees, the measure of angle B is eighty degrees and the measure of angle C is x.

Since we know that sum of measures of all the three angles of any triangle equals to 180 degrees.

Let us set sum of measures of all angles of our triangle equal to 180 degrees.

A+B+C=180^{o}

Upon substituting our given values in our equation we will get,

55^{o}+80^{o}+x=180^{o}

135^{o}+x=180^{o}

x=180^{o}-135^{o}

x=45^{o}

Therefore, the measure of angle x equals to 45 degrees.

Firlakuza [10]

Answer:

18.75=p

s=14.06

b=2.34

Step-by-step explanation:

37.75=b+s+p

-4

33.75=b+s+p

s=3/4p

b=1/6s

33.75=1/6(3/4p)+3/4p+p

33.75=3/20p+3/4p+p

(33.75=18/20p+p)20

675=18p+p)/18

37.50=2p)/2

18.75=p

s=3/4p

3/4(18.75)

s=14.06

b=1/6s

1/6(14.06)

b=2.34

37.75-4=18.75+14.06+2.34=35.15

A truffle recipe uses 10 ounces of dark chocolate to make 60 truffles. How many truffles can a baker make with 3 pounds of dark
maxonik [38]

Answer:

240

Step-by-step explanation:

ok, so first you look closely at the problem. convert pounds to ounces, since you dont have enough to do it the other way. so if 1 pound is 16 ounces, 3 pounds is 48. he has 48 ounces. if 10 ounces makes 60, 40 ounces makes 240. now you have 8 left. now im not sure about this part, but if you took the 8 left over, and if 10 ounces makes 60, 8 ounces makes 48 more.
