Answer:

60°

Step-by-step explanation:

The sum of all three triangle angles add up to 180°. To solve for the last angle, add the sides you know together and subtract the sum from 180. This will leave you with the third angle's measurement,

40 + 80 = 120

180 - 120 = 60

What are the solutions of the following system x2+y2=25 , 2x+y=-5
tia_tia [17]
Y=5-2x
x^2 + (5-2x)^2 = 25

x^2 + 25-20x+4x^2 = 25

x^2 +4x^2-20x+25=25
5x^2 -20x=0

x=0 and y=5

Write a problem that requires multiplying two decimals to find the answer. The product must have two decimals places.
julsineya [31]

Answer:

3.5 * 6.7 = 23.45

Step-by-step explanation:

(I am assuming you know how to do 2-digit by 2-digit problem, but just in case you don't I am putting in how to do it.)

You would multiply the problem like a normal 2-digit by 2-digit problem.

- multiply the ones places (5*7=35)

- you bring the 3 of the 35 and put it above the other 3

- you then do 7*3=21+3 because you moved it.

-so the first part of the question would be 35*7=245

-you go below the 5 and put a zero because you dont need the ones place anymore.

-you then do the same thing but with the tens place instead.

- You would then get 35*6=210, but you can't forget the zero.

- you would then add 245+2100=2,345

- But don't forget the decimals. you have to add the decimals to the answer.

- you count how many numbers that are behing both numbers, in this case it would be two.

- you then put the decimal after the ones and tens place.
