Ok if you look at the first to equations carefully you will see that 2 things have changed between the 2. the "+c" is now "-c" and the "10" is now "3"
if we think about it you will see that c=7. well how do we know. when c or 7 was taken away from the problem it left you with 3
so that means a+b=3
we dont need to know what the exat value of a or b is.
so a+b +3c
(3) + 3(7)
3 + 21
24
a+b+3c=24
The answer is B because it has a days to work in and if you’re working at the same job every day it will take 12 days a week 8-2(2-4)=2
Answer:
46degrees
Step-by-step explanation:
From the question, we are told that both triangles are similar, hence;
<E = <S
<D = <R
<F = <T
From triangle DEF
<D + <F + <E = 180
Since <D = <F = 67
67 + 67 + <E = 180
134 + <E = 180
<E = 180 - 134
<E = 46degrees
Since <E = <S, hence the measure of <S is 46degrees
