I need to understand ratio plz help
Lady_Fox [76]
If your looking for basically the definition of ratio it means, lets say we have 2 can of milks, and 3 cans of cookies, if it asks find the ratio of milks first then cans it is 2:3, or if it asks find the ratio of cans of milk to cookies, which is 3:2 or part to whole which means 3+2 or 2+3= 5 is whole and if they say part would be milk then 2:5 or if its cans of cookies to whole its, 3:5. I hope this helps ask me anything that you didn’t understand!

To find the area of a figure like this, first split this into two shapes to make things simpler: a 10 by 8 rectangle, and a triangle with a height of 5 and a base of 4. To find the dimensions of the triangle, notice that the base of the entire figure is 12 and once you split the figure into a rectangle and a triangle, you get one side that is 8 which means the base of the triangle must be 4. Now that we know the dimensions of each figure, start by finding the area of each one. To find the area of the rectangle, multiply its length by its width, or 10*8. This would give you 80. Then, find the area of the triangle, which is multiplying its base and height and dividing it by two. This would be (4*5)/2. This would equal 10. Now that we have the area of both the sections in the figure, add them together and you get your answer as 90.

aalyn [17]

Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc EH

Remember that the measure of the complete circle is equal to 360 degrees

so

arc\ EH+arc\ EF+arc\ FG+arc\ GH=360^o

Remember that

arc\ EF=m\angle EDF ----> by central angle

arc\ FG=m\angle FDG ----> by central angle

arc\ GH=m\angle GDH ---> by central angle

substitute the given values

arc\ EH+55^o+70^o+110^o=360^o

arc\ EH=360^o-235^o=125^o

step 2

Which arc is congruent to Arc E H?

we know that

arc\ EFG=arc\ EF+arc\ FG=55^o+70^o=125^o

therefore

arc EH is congruent with arc EFG

or

arc EH is congruent with minor arc GE
