2. 22.42
3. 74.52
Answer:
A- SAS
Step-by-step explanation:
The statements tell you the outer two lines are congruent and the top two angles as well, then through the properties of equality you know the inner line is congruent to itself. That means you have two sides and an included angle making it SAS.
The answer is 24. think of x as the original amount, and y as the new
amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y,
which is what we need, and you have x/1.5 = y as well as x-12 = y. Use
the equal values method and make an equation x/1.5=x-12. solve this
equation to get x, which is 36. to figure out the new amount, y, you
need to subtract 12, which would help you get 24 as your final answer.
Answer:
150m^2
Step-by-step explanation:
Given data
a=8m
b=17m
h=12m
We know that the expression for the area of a trapezoid is given as
Area= (a+b/2)*h
substitute
Area= (8+17/2)*12
Area= 25/2 *12
Area= 12.5*12
Area= 150 m^2
Hence the area is 150m^2
