Answer:
a. 125 degrees
b. 62 degrees
c. 58 degrees
d. 130 degrees
Step-by-step explanation:
I assume these are the inner angles of the polygons.
remember, for a polygon with n sides we can fully split it into n-2 triangles without overlap.
each of these triangles has an angle sum of 180 degrees.
to get the total inner angle sum of the polygon, we need to multiply 180 by (n-2) (= the number of triangles).
out of that total we can then calculate the size of the missing angle.
a. 6 sides, therefore 4 triangles
4×180 = 720 degrees
the missing angle is
angle = 720 - 88 - 152 - 125 - 105 - 125 = 125
b. 5 sides, 3 triangles
3×180 = 540 degrees
angle = 540 - 109 - 111 - 140 - 118 = 62
c. 4 sides, 2 triangles
2×180 = 360
angle = 360 - 60 - 142 - 100 = 58
d. 7 sides, 5 triangles
5×180 = 900
angle = 900 - 90 - 120 - 140 - 150 - 120 - 150 = 130
You first have to know how long each bead is and if its inches, centimeters, ect.
Answer:
107
Step-by-step explanation:
Using PEMDAS (or GEMDAS), we know which things to solve for first and which to not.
In the parenthesis there is an exponent. We have to solve that fist and 10^2 is 100, so we end up with (3+100)+4.
It doesn't really matter what order we do now because adding things in different orders doesn't change the outcome. 3+100+4=107.
Answer: the answer is 24 CO3 0
Step-by-step explanation:
I'd use the point-slope form, because it'd require the least amount of work.
The slope of this line is 3/1, or just 3.
Thus, y = mx + b becomes 3 = 3(1) + b, and b = 0. Thus, we get y = 3x (ans.)
