if the measurements of a quadrilateral is 68 degrees and52 degrees and 125 degrees what is the missing angle​
alex41 [277]

Answer:

Step-by-step explanation:

Quadrilaterals add up to 360 degrees.

Let the missing angle = x

68 + 52 + 125 + x = 360

245 + x = 360

Subtract 245 from both sides.

245 - 245 + x = 360 - 245

Combine

x = 115

What is the value of this expression when c= -4 and d = 10?
Alisiya [41]

Answer:

c + d^2 = 96

Step-by-step explanation:

Given

c = -4\\d = 10

Required

Find c + d^2

To find c + d^2, we simply substitute 10 for d and -4 for c in the given expression.

The step is as follows:

c + d^2

Substitute c = -4\\d = 10

c + d^2 = -4 + 10^2

c + d^2 = -4 + 10*10

c + d^2 = -4 + 100

c + d^2 = 96

The expression cannot be solved any further; so, we can conclude that when d = 10 and c = -4, c + d^2 = 96
