0.9b + 2 is the correct answer
Answer:
sqrt 51
Step-by-step explanation:
You should use the pythagorean theorem, which states a^2+b^2=c^2. So the missing side length for the smaller triangle is sqrt{2^2+3^2}=sqrt{4+9}=sqrt{13}. And the side length x is sqrt{8^2-sqrt{13}^2}=sqrt{64-13}=sqrt{51}
The answer is 2197 inches cubed
M<S = 1/2(80-40)
m<S = 40/2
m<S = 20
answer is A. 20
Angle x = 83 degrease. all angles, when added, of a triangle equal 180 degrease, using this, we can add the two we know together and then subtract them from 180 to get our answer. 44 + 53 = 97, 180 - 97 = 83.
Hope this Helps, Good luck!
