Answer:

61 degrees

Step-by-step explanation:

Since one of the sides is 102, the opposite one will be the same.

so,

102+102+95

= 299

The total is 360 degrees

360-299

= 61 degrees

Answer:

$9w^{2}$

Step-by-step explanation:

An easy way to find the GCF of different numbers is to list out all of their factors. In this case, the coefficients share multiple factors, but the largest is 9.

Additionally, when dividing variables with different powers you subtract the exponents. So, if you were to divide $\frac{w^3}{w^2}$ the final answer would be $w$ because 3-2 is 1. So, to find the GCF of like variables find the biggest number that can be subtracted from all of them. In this case, that is 2; therefore, the GCF of the variables is $w^2$ . Put the 2 parts together for the final answer $9w^{2}$ .
