Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
In each question sum the 3 angles and equate to 180
3
a.
x + 8x + 90 = 180
9x + 90 = 180 ( subtract 90 from both sides )
9x = 90 ( divide both sides by 9 )
x = 10
b
4x - 5 + 3x + 11 + 90 = 180
7x + 96 = 180 ( subtract 96 from both sides )
7x = 84 ( divide both sides by 7 )
x = 12
4.
4x + 2x + 11 + 19 = 180
6x + 30 = 180 ( subtract 30 from both sides )
6x = 150 ( divide both sides by 6 )
x = 25
5.
5x + 20 + 2x - 5 + 3x - 10 = 180
10x + 5 = 180 ( subtract 5 from both sides )
10x = 175 ( divide both sides by 10 )
x = 17.5
Answer:
1. $1666.17
2. $666.17
Step-by-step explanation:
The bonus of $1600 that Kira gets is invested for 3 years at an annual interest of 1.36% compounded annually.
Therefore, after 3 years Kira will have in her account
dollars (Answer)
Therefore, the amount of interest earned by Kira's investment after 3 years will be
$( 1666.17 - 1600 ) = $666.17 ( Answer )
Answer:

4.791666666666667
2) multiply 4.791666666666667 by 33.6
161
Done! Your answer is 161 calories in a 33.6 gram bag. Or just 161.
Hope this helps!
Answer:
C -2 or 1
Step-by-step explanation:
So from the equation you have x^2-x-1=-2*x+1
x^2-x-1+2*x-1=0
x^2 +x -2 =0
D= 1^2 -4*(-2)= 1+8=9
x = (-1+-3)/2
So x is either (-1+3)/2=2/2=1
or (-1-3)/2=-2
