Answer:
115°
Step-by-step explanation:
The sum of angle measures of a pentagon is 540°, so your unknown angle can be found from ...
... 103° + 100° +110° +112° +unknown = 540°
... unknown = 540° -425° = 115° . . . . . . . . subtract 425° from both sides

<em>Angles of a polygon</em>
The external angles lf a convex polygon always sum to 360°. The sum of internal and external angles is, of course, 180°. So, an n-sided polygon has internal angle measures that sum to ...
... n×180° - 360° = 180°×(n -2)
Thus, a pentagon has internal angles that sum to ...
... 180°×(5 - 2) = 540°

Answer:
D) 205
Step-by-step explanation:
Given : Cost = 83 - 2 (time taken) + 6 (materials) + 1.1 (marketing cost)
Relationship Equation : y = 83- 2x1+ 6x2 + 1.1x3
Given, time (x1) = 5 , materials (x2) = 4 , marketing cost (x3) = 100
So, putting values, Cost : y = 83 - 2 (5) + 6 (4) + 1.1 (100)
= 83 - 10 + 24 + 110 = 207
The closest to this calculated estimated figure ie 207, is 205.
