Answer:
EFG
Step-by-step explanation:
Perimeter is 30
Area is also 30.
Add the numbers to get the perimeter and then use 1/2bh to get the area. <span />
Answer:
![(-8)^2\neq-64](https://tex.z-dn.net/?f=%28-8%29%5E2%5Cneq-64)
Step-by-step explanation:
Using the distributive property to expand, we have
![(-8x^2y^2)^2=(-8)^2(x^2)^2(y^2)^2.](https://tex.z-dn.net/?f=%28-8x%5E2y%5E2%29%5E2%3D%28-8%29%5E2%28x%5E2%29%5E2%28y%5E2%29%5E2.)
Squaring each term, we have
![(-8x^2y^2)^2=64x^4y^4.](https://tex.z-dn.net/?f=%28-8x%5E2y%5E2%29%5E2%3D64x%5E4y%5E4.)
The mistake was that
not
Using the fact that
the right answer would be
.
We can use the tangent ratio, where tan(x)=opposite/adjacent. In this question, FT is the 'opposite', TV is the 'adjacent' and 43° is 'x'.
Let's substitute the values into the equation, and rearrange to find the length of FT:
tan(43)=FT/53
× both sides by 53
53tan(43)=FT
Using a calculator, the answer to this equation gives us 49.42329957. Thus, the answer is D. 49.42
