Answer:
90/23
Step-by-step explanation:
First, you want to start in the parentheses. 5-6=-1, then multiply it by -2. Since a negative multiplied by a negative is a positive, -2*-1=2. -3^2=-9. 2+8=10. Then -9 times 10= -90. Then, we move on to the bottom. 5--2=7. 4^2=16, and -2(2)=-4. So -5(7) + 16-4=-23. Now, the equation should look like this, -90/-23. Put the negatives together and you get 90/23.

Answer:
4.58 ft
Step-by-step explanation:
Pythagoras Theorem:
a^2 +b^2 = c^2
b^2 = c^2 - a^
b^2 =11^2 - 10^2
b^2 = 121 - 100
b^2= 21
the heigh = √21 = 4.58
Answer: 4.58 ft
