Assuming that the triangle is a right triangle, we can reverse engineer the Pythagorean theorem (a^2+b^2=c^2).
60^2 + x^2 = 61^2
3600 + x^2 = 3721
x^2 = 3600 - 3721
x^2 = 121
x = sqrt121
x = 11
Answer:
x= 12 and y= 2
Step-by-step explanation:
First you would line up the equations so the x's and y's are on top of each other. Then you would multiply x+y=14 by 3 to give you 3x+3y=42. After that you subtract 2x-3y=30 and 3x+3y=42 to give you an answer of x=12. After that, you plug in x with 12 in the equation x+y=14. You subtract 12 from both sides to get an answer of 2. So ur solution is (12,2)
Answer:
what subject is this in
Step-by-step explanation:
2.75=2 3/4 because you would say 2.75 as two and seventy-five hundredths. Seventy-five hundredths is just like 3 quarters out of 4 because 1 quarter=25. 2=50. 3=75. So, 2.75 as a fraction in simplest form is 2 3/4.
