Answer:
she worked 17 hours
Step-by-step explanation:
first you subtract 256-40
then you get 216 and divide by 8
then you get 27 as an answer
Answer:
The evaluation of the equation 3 .912+s=5.313 yields; s = 1.401
Evaluation of one variable equation
According to the questions;
We are required to evaluate the equation; 3 .912+s=5.313
Hence, we must subtract 3.912 from both sides of the equation as follows;3 .912+s -3.912 = 5.313 - 3.912.s = 1.401
Step-by-step explanation:
mark me brainliest!!
The answer is C because 3/4 is the biggest of them all and the only one saying that is C.
(1/4)x+1=32
(1/4)x=31
X=31*4
X=124
Part (A)
We have n = 5 sides, so the measure of any exterior angle of a regular pentagon is E = 360/n = 360/5 = 72
Each interior angle is therefore 180-E = 180-72 = 108 degrees.
---------------
Alternatively, you could use the formula below with n = 5
i = interior angle
i = 180(n-2)/n
i = 180(5-2)/5
i = 180(3)/5
i = 540/5
i = 108

<h3>Answer: 108 degrees</h3>
====================================================
Part (B)
We're told that CDF is 70 degrees. From part (A) we know that angle CDE is 108 degrees, so this must mean that angle EDF is 108-70 = 38 degrees.
Similarly, angle FEA is 85 degrees, which subtracts from angle AED to get 108 - 85 = 23 degrees. This is the measure of angle DEF.
So far we found
angle EDF = 38
angle DEF = 23
Let's call these x and y for shorthand. Let z be the missing third angle of triangle DFE.
So,
x+y+z = 180
38+23+z = 180
61+z = 180
x = 180-61
x = 119
Interior angle DFE is 119 degrees.
Note how 90 < x < 180 showing we have an obtuse angle. It is not a reflex angle because the statement 180 < x < 360 is false.
So we subtract the value of x from 360
360-x = 360-119 = 241
This is the reflex angle DFE

<h3>Answer: 241 degrees</h3>
