It should be the second image on this list. I hope this helps! ^^
Answer:
yes
Step-by-step explanation:
Y=mx+b
in you're equation -1/2 is you're slope and 1/4 is what is going by
m=slope
b=moving by
Answer:
x=50
Step-by-step explanation:
Let's look at the red angle. if a flat line makes the angle 180, and the outer angle is 120, subtract 120 from 180. This will give you 60. Now every angle of a triangle added together will give you the sum of 180. So you already have 60 and 70, which make 130 all together. Subract 130 from 180 - (180-130) - and you'll get the result of 50.
I would tell you how to do it but its a very hard thing to explain
Answer:
1:3
Step-by-step explanation:
Please study the diagram briefly to understand the concept.
First, we determine the height of the isosceles trapezoid using Pythagoras theorem.

The two parallel sides of the trapezoid are 8 Inits and 4 units respectively.
Area of a trapezoid 
Area of the trapezoid

For an equilateral triangle of side length s.
Area 
Side Length of the smaller triangle, s= 4 Units
Therefore:
Area of the smaller triangle

Therefore, the ratio of the area of the smaller triangle to the area of the trapezoid
