Answer:

90

Step-by-step explanation:

The sum of the angles is 360 degrees since this is a quadrilateral

x+2x+80+145 = 360

Combine like terms

3x +225 = 360

Subtract 225 from each side

3x+225-225 = 360-225

3x =135

Divide each side by 3

3x/3 = 135/3

x =45

We want to find angle S

S = 2x = 2(45) = 90

Evaluate the expression: (–2)2 + (–42) + (18 – 23).
marta [7]

Answer:

-51 (no options are matching)

Step-by-step explanation:

Given: (–2)2 + (–42) + (18 – 23).

we know, 2*2 = 4, and in integer multiplication if any negative integer is multiplied with positive integer, then the result will have a negative sign.

= -4 + (-42) + (18 – 23)

Here, we have open the brackets, and written the respective signs with the integers,

= - 4 - 42 - 5

now, we will perform the integer addition. Adding all the positives together & he negative numbers together

= -51

PS: It happens to be that none of the given options match with the correct answer. But, i have solved taking the expression, i hope it helps
