Let x be the first number
Let y be the second number
x+y=61
x-y=37 --> x=37+y
(37+y)+y=61
37+2y=61
2y=61-37
2y=24
y=12
x+y=61
x+12=61
x=61-12
x=49
Therefore the numbers are 49 and 12
Hope I helped :)
X² - 21x + 110
first you break it up into two parenthesis & since x is squared you need two x's
since 110 is positive and 21 is negitive, both of your signs need to be negitive
(x - ?)(x - ?)
then you need to think! what are the factors of 110?
Which of these factors add up to 21? those factors go in the parenthesis
Does this Help? Let me know if you need anything!

Answer:
do you have a picture of the triangles?
Step-by-step explanation:
3sinx+1=sinx
2sinx+1=0
2sinx=-1
sinx=-1/2
x=sin^-1 (1/2) = 30 =

/6 (when finding the inverse, always take the positive value, ignore the negative sign)
x is therefore negative in 3rd and 4th quadrant
Therefore values of x are:
180+30=210 = 7

/6
360-3=330 = 11

/6
