Cef is equilateral so
l=m=n
l+m+n=180
so l=m=n=60
as l=i <span>When two lines intersect, the opposite (X) angles are equal:
</span>or i+j+k=180
i+j=135 eq1
j+k+l=180
j+l=135 eq 2
eq1-eq2
gives i=l
so i=60
g=40
g+h+i=180
h=80
Answer:
I would make sure to note keywords in the problem/question such as (percent) off, (percent) tax, etc. These words can determine if the original number will become higher or lower after the percent is applied to the original number. For example, if there is a price for a t-shirt of $15, and there is a <em>tax</em> of 13%, the original price will <u>increase</u>. On the other hand, if there is a sale for pants at the local department store and you are buying a pair of pants that cost $25 with the sale being 10% <em>off</em>, the price will <u>decrease</u>.
Step-by-step explanation:
y - y1 = m(x - x1)
y + 1/2 = 3(x - 2)
y = 3x - 6 - 1/2
y = 3x - 13/2
I can't draw here but a 1/2 slope rises 1 and runs 2 so go up 1 unit and right 2 units (if it is a positive slope) 1 unit is 1 square on the graph/coordinate plane
20•9=180
180•5=900
You have to brake down the problem to it simplest form
