Answer:
x = 23°
Step-by-step explanation:
Looking at the diagram above, we can see that it is Pentagon.
The sum of interior angles in a Pentagon (5 sides polygon) = 540°
This is because in a Pentagon, from the vertex we can draw 2 diagonals that would result in 3 triangles.
Sum of angles in a triangle = 180°
Hence, the sum of angles in a Pentagon = 3 × 180°
= 540°
Hence,
540° = 85° + 5x° + 5x° + 5x + 5° + 5x - 10°
540° = 85° + 5° - 10°+ 5x° + 5x° + 5x° + 5x°
540° = 80° + 20x°
540° - 80° = 20x°
460° = 20x°
x° = 460/20
x = 23°
Therefore, the value of x = 23°
Answer: B. 1,995
Step-by-step explanation:
Convert hours to minutes
60+45= 105
Multiply
19*105= 1,995
SO, it's B. 1,995
Answer:
500cm or 5 meters
Step-by-step explanation:
The ratio of drawing and field is 1:90.
So we have to make 450 m into cm.
450 -> is 45,000
Now we can make 2 fractions,

Cross multiply
90*x = 90x
1*45000 = 45000
90x = 45000
Divide 90 to both sides
x = 500cm
<em>Thus,</em>
<em>the drawing's field is 500cm or 5m long.</em>

Answer:
The estimated sum is ≈10
Step-by-step explanation:
This depends on how your professor wants you to estimate sums. Logically, though, a value of nearly 4 and a value of just over 6 add to about 10. The exact answer would be a bit over 10, at ≈10.14117
