Answer:
Answer A (or C. Both were very close)
Step-by-step explanation:
I don't know what "please only answer if you know not to ask a question" means.
Since ∠ADB is 90° and ∠BAD is 36°, then ∠ABD is 180-90-36 or 54°.
You could just try using the Pythagorean Theorem for all the answer choices.
(a²+b²=c² where a and b are the legs and c is the hypotenuse)
A.
11²+8²=c²
121+64=c²
c=
c ≈ 13.60
B.
I don't need to prove this because the shorter legs' sum is greater than the hypotenuse and will not make a triangle.
C.
15.1²+11²=c²
288.01+121=c²
c=
c ≈ 18.68 ≈ 18.7
D.
I don't need to prove this because the shorter legs' sum is greater than the hypotenuse and will not make a triangle.
I think answer A is the best since it rounds closer to the answer in the row. It was pretty close between C and A so you can decide if you'd like but I suggest A because it's a closer rounding.
Answer:
Numbers of pitchers of lemonade = 8
Step-by-step explanation:
Given as
Amount of lemonade concentration = of a cup
Now, of a cup of concentration mix with
of water
So, -
=
of cup of lemonade,

Answer:
square units
Step-by-step explanation:
The area of a triangle can be calculated by multiplying the triangle's base by its height, and then dividing the result by . As an algebraic expression, this would be
, where
is the triangle's base and
is the triangle's height. In this case, we know that
and
. Therefore, the area of this triangle is
square units. Hope this helps!
