Answer:
m∠C = 26°
m∠D = 108°
m∠E = 46°
Step-by-step explanation:
Set up the equation adding the expressions together to equal 180 (sum of all angles in a triangle)
(2x) + (x+3) + (5x-7) = 180
Remove the parentheses
2x + x+ 3 + 5x - 7 = 180
Add like terms
8x - 3 -7 = 8x -4 = 180
8x - 4 = 180
Add 4 on each side to cancel it out on the right
8x - 4 = 180
+4 = +4
8x = 184
Divide each side by 8 to get the variable by itself
8/8 =1 184/8 = 23
x = 23
Substitute x in eac expression
2x = 2(23) = 46°
x + 3 = 23 + 3 = 26°
5x - 7 = 5(23) - 7 = 115 -7 = 108
Chek it by adding all the degrees to make sure it equals 180
46 + 26 + 108 = 72 + 108 = 180
Answer:
x=0,![\sqrt[6]{5}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B5%7D)
Decimal form,
x=0,1.30766048......
Step-by-step explanation:
x
=
x
-
=0
(take x as a common factor)
x(
-
)=0
So,
x=0 and
-
=0
for
-
=0
(add
for both sides)
=
x=
(multiply 3 by 2)
x=![\sqrt[6]{5}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B5%7D)
So,
x=0,![\sqrt[6]{5}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B5%7D)
38% of 21,515,714 is 8175971.32 which can be rounded to 8,175,971.

Answer:
2
Step-by-step explanation:
Ok so basically you want a number that is evenly divisible by 4. Or in other words 4 x ? = 691,61#
The easiest thing to do is start with a zero there and divide it by 4 to see what you get.
691,610 / 4 = 172,902.5
Since this is not evenly divisible by 4 let's round it up to the next whole number and multiply by 4
4 x 172,903 = 691,612
So the digit you can put on the end of the number is 2
