I believe it would be the second one.
Answer:
Area = 144 ft^2
Step-by-step explanation:
Remark
Use the Pythagorean theorem to find the length of the legs. Then multiply them together and divide by 2.
Equations
a^2 + a^2 = c^2
Area = (1/2) * a^2
Givens
c = 24
Solution
Remember that an isosceles triangle has 2 equal sides. Both legs of the triangle are equal to a.
a^2 + a^2 = c^2 Combine
2a^2 = 24^2 Expand
2a^2 = 576 Divide by 2
2a^2/2= 576/2
a^2 = 288 You might just as well leave this. go to area
Area = 1/2 (288)
Answer: Area = 144 ft^2
Answer:
A. (3, 10)
Step-by-step explanation:
You are told that ...
(x, y) = (number of accessories, dollars)
and you are told that ...
number of accessories = 3
dollars = 10
so the ordered pair is ...
(x, y) = (3, 10) . . . . Point A
Answer:
346 ( 3 s.f )
Step-by-step explanation:
pi r square is the formula
Remember that opposite angles are congruent.
So,
we know that <E= <G
That is 45+45= 90 degrees
We also know that consecutive angles are supplementary. E and F would equal 180 degrees.
180-45=135
<F= 135 degrees.
We can check this by seeing if all the angles add up to 360 degrees/
135+135+45+45
=360 <== this works
I hope this helps!
