Answer:
b = 65 degrees
Step-by-step explanation:
As we can see, the line that angle b and 115 deg correspond to is a straight line. A straight line <em>always</em> measures at 180 deg.
Because of this principle, we know that:
We can simplify this one variable equation now:
Now solve:
And this makes sense. Just by eyeballing the angle, we can see that it is under 90 degrees.
So, b = 65 degrees
Answer:
The answer is C.
Step-by-step explanation:
5×1.1=5.5.
18 divided by 4 gives 4r2 so we could do 32 different ways
Hi!
Now I can answer.
I used systems of equations That is how I solved it. Always remember to check your answer by plugging it back into the word problem. If you aren't comfortable with systems of equations then find some help in this area.
(.85x)1.25=y new line
x + 10=y new line
x=y-10 new line
(.85(y-10))1.25=y new line
(.85y-8.5)1.25=y new line
1.0625y-10.625=y new line
.0625y=10.625 new line
y=170 new line
x=160
Hope this helps!!
