we know that
Two angles are supplementary if their sum is equal to
degrees
in this problem we have


so
therefore
<u>the answer is</u>
The two angles are supplementary
18 with a remainder of 26 I got this by using a long division calculator I hope this helps you
A) you must plug in 50 for variable F and solve for C
C=

(50-32)
C=

(18)
C= 10
50 degrees fahrenheit is equal to
10 degrees celsius B) you must solve the equation for F
C=

(F-32)
C/

=F-32
C/

+32=F
F= C/

+32
dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as
F=
C +32
now you just plug in 50 for the variable C in the new equation
F=

(50) +32
F= 90 + 32
F= 122
50 degrees celsius is equal to
122 degrees fahrenheit
hope this helped!
