So for the first one, you would have to multiply 2 six times. and then 2 with a -4 exponent is a little challenging. Okay, you would have to make it a fraction. so it would be 1/16. then you would just multiply 2 seven times.
We know the sum of all the angles in a quadilateral is equal to 360. so,
it would be: 360 - (74+93+117)
= 360 - 284
= 76 degrees
So, Your final answer is 76 degrees.
Hope this helps!
The answers are: -5.3, -6.5
