Answer:

A triangle is normally 180 degrees only.

Step-by-step explanation:

So, you have one 90 degree angle, and on 42.7 degree angle. Add those up to 132.7. Now, you would subtract that from 180, meaning that the answer is A, 47.3.

What value is added to both sides of the equation x2 − 2x = 10 in order to solve by completing the square?

VLD [36.1K]

Hi,
Answer C

$x^2-2x=10\\
x^2-2x+1=10+1\\

\Rightarrow\ (x-1)^2=11\\
\Rightarrow\ (x-1)^2-11=0\\
\Rightarrow\ (x-1)^2-( \sqrt{11})^2=0\\
\Rightarrow\ ((x-1)+ \sqrt{11})((x-1)- \sqrt{11})=0\\
\Rightarrow\ x-1+ \sqrt{11}=0\ or\ x-1- \sqrt{11}=0\\

\Rightarrow\ x=1- \sqrt{11}\ or\ x=1+ \sqrt{11}\\
