Here the given expression is
And the given value of x=5 . We need to find the value of y when x=5. And for that, we need to plug 5 for x .
So when x=5, y= 7.6
Answer: 27.69⁰
Step-by-step explanation:
Formula for finding the internal angle of a regular polygon is
( 2n - 4 )right angle triangle or
( 2n - 4 )90°, it can also be broken down by factorizing the expression since 2 is common,
( n - 2 )180 or supplementary
Now to find the value of n which correspond to the number of sides the polygon has, we equate the formula to the angle sum of the polygon.
( n - 2 ) × 180° = 1980°
open the bracket
180n° - 360° = 1980°
180n° = 1980° + 360°
= 2340
To find n, divide by 180 which is the coefficient of n
n = ²³⁴⁰/₁₈₀
= 13
The polygon has 13, sides
To find the measure of each angle,
Recall, the sum total of external angle = 360⁰
Therefore, to find the value of each of the angles, we divide 360 by n which is 13
³⁶⁰/n
= ³⁶⁰/₁₃
= 27.69⁰
Answer:
just turn the percentage into a decimal then you multiply or add
Answer:
D. 8.053 x 10^4
Step-by-step explanation:
Given :
7.17 x 10^4 and 8.17 10^5
The number in between the two Given numbers should be greater Than 7.17*10^4 but less than 8.17*10^5
A. 6.92 x 10^4 - this is less than 7.17 * 10^4 ; hence doesn't fit in
B. 7.2 x10^9 - this is greater than both values, hence, doesn't fit in
C. 7.57 x 10^3 - this is less than 7.17*10^4 ; hence does not fit in
D. 8.053 x 10^4 - this fits in as it is greater than 7.17*10^4 and less than 8.17*10^5 ; hence, it is the correct answer.
372 is the answer.
(9*6*3)+(10*7*3)=372
