Therefore, <2 is going to be equal to the m< the corresponding angle in the other triangle. <2 = 61°

Hey there! I'm happy to help!

Let's look at our diameters.

$1*10^2^1\\5*10^2^2$

We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.

$\frac{5*10^2^2}{1*10^2^1} \\$

We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x

$\frac{5*10^2^2}{1*10^2^1} = 5*10=50$
