Answer:
4√3 cm^2
Step-by-step explanation:
30 60 90 right triangle
The ratio of short leg : long leg : hypo. = x : x√3 :2x
Given Hypo BC = 4 = 2 * 2
so Long leg = 2√3
Area of ABC = 1/2 (b)(h)
= 1/2 (4)(2√3)
= 4√3
Answer
4√3 cm^2
Perimeter = 3 x 4 = 12 cm (you asked from other, so I answered for you as well)
Answer:
option 2
Step-by-step explanation:
Answer:
13.5 meters
Step-by-step explanation:
25 / 2 = 13.5
because if a human is 3 meters tall and cast 2 times the length of himself then if a building casts 25 meters then it should be 2 times less than its shadow.
You would first plug in y to the other equation. It doesn’t matter which one you do. So it would look like...
2x=10x-16
Then you would move the like terms to one side
2x-10x=-16
-8x = 16
Then make the x alone by dividing -8 on both sides to solve for x.
X= 16/-8
x = -2
Hope this helped!
The simplified expression would be 4y^6 / x^5. However, I had a hard time distinguishing which numbers were exponents or not in your question.
