Answer: 8 hrs
Step-by-step explanation:
divide 228 by 12 to get a unit rate of 19 and then divide 152 by 19 to get 8
Answer:
28
Step-by-step explanation:
First multiply 8 by 4 to get 32. Now there is a small triangle in the bottom. Multiply 4 by 2 to get 8. Then divide 8 by 2 to get 4, the area of the triangle. Now lastly 32-4 to get 28 square units, the area.
The sides of an equilateral triangle are equal length, so ...
GH = FH
3x-9 = 2x-2
x = 7 . . . . . . . . add 9-2x
Then the side lengths are
FG = x+5
FG = 7 +5 = 12
x = 7
FG = GH = FH = 12
Let's solve for value of values of x and y ~
According to Angle sum property of triangles :
Now, solve for y ~
Now, by the results we got, we can conclude that :
The two triangles are not similar because 70 + 58 + x = 180 means x = 52° and 70 + 49 + y=180 means y = 61°
