Answer:
a) ∠a = 72°
∠b = 108°
b) ∠ = 56°
c) ∠m = 95°
Step-by-step explanation:
- Sum of interior angles of a polygon = (n − 2) × 180
(where n is the number of sides)
- If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle.
The sum of the exterior angles of a polygon = 360°
- The sum of angles on a straight line = 180°
a) This shape is a regular polygon with 5 sides.
Therefore, sum of the interior angles = (5 - 2) x 180 = 540°
Therefore, ∠b = 540 ÷ 5 = 108°
∠a = 180 - 108 = 72°
b) The sum of the exterior angles of a polygon = 360°
Therefore, 55 + 63 + 52 + 44 + 90 + = 360
304 + = 360
= 360 - 304 = 56°
c) The sum of the exterior angles of a polygon = 360°
Therefore, 40 + 40 + 35 + 40 + 50 + 60 + m = 360
265 + m = 360
m = 360 - 265 = 95
Answer:
The globe represents the whole earth, whereas a map may represent the whole earth or just a part of it. A globe can be used to get a broad-level picture of the world while maps provide more specific information about different places.
Step-by-step explanation:
The answer should be A. In order to solve these half-life problems, I encourage you to find an algebra calculator online, and plug in these numbers. The remaining grams goes in front, so 3.
The entire equation should look something like 3 = 15(1/2)^t/4.95
The 4.95 represents how long it takes before the sample halves, t is your answer, 1/2 represents the value halving every 4.95 hours, 15 is the initial sample size, and 3 is the end result that remains.
The overall answer should be about 11.5 hours, as per an algebra calculator.
Hope this helps solve any other similar problems
Answer:
-5/2 because there is -5y/2 but we have to take coefficient only so -5/2
