<h2>30.00</h2>
Step-by-step explanation:
Given the expression 
, the following steps must be taken to evaluate the expression.
From the calculator, the value of y wil give;
Hence 
.
Answer:
y = x - 6
Step-by-step explanation:
the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.
now, let's calculate the slope:
1-2/7-8= -1/-1 = 1
here is the equation we currently have solved: y = x + b
now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.
let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.
2= 8 +b
2 -8=b
b=-6
and now we have our final equation!
y = x - 6
hope this helped! please let me know if you are confused about anything i did
<span>88.3 : 100 = 86.7 : x
x = 98.18
100-98.18=1.81 (rounded 1.8)
----------------------------------------------
(88.3-1.8%=86.7)</span>
A (42 degrees) bc the angles are across from each other so they’re equal
