Angle on a straight line sums up to 180
so
72+x + x+130 = 180
2x = 180-72-130
2x =-22
x= -11
so Angle on the LHS is 61°
while angle on the RHS is 119°
Answer:
2(2 + 3) = 2(2) + 2(3)
Step-by-step explanation:
The first one shows the associative property.
In the second one, the paranthesis is being solved first, therefore the rule of PEMDAS is being applied.
The last one displays the commutative property.
Answer:
37.5%
Step-by-step explanation:
So the original fraction is 3/8 and we can’t simplify it so we gotta turn it into a percent, and we can do that by dividing 3 and 8nto get .375 so the percent is 37.5%.
1) The equation of the parallel line in Slope Intercept Form is; y = -x - 1
2) The equation of the perpendicular line in Slope Intercept Form is;
y = ³/₂x - 4
<h3>How to write equation in Slope Intercept Form?</h3>
1) When two lines are parallel, it means their slopes are the same.
Formula for equation in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Thus, slope of y = -x + 1 is m = -1.
Equation of parallel line is;
(y - (-5))/(x - 4) = -1
y + 5 = -x + 4
y = -x - 1
2) When two lines are perpendicular, it means their slopes are the negative inverse of each other. Thus;
Slope of line = -2/3 and so slope of perpendicular line = 3/2. Thus, equation of new line is;
(y + 1)/(x - 2) = 3/2
2y + 2 = 3x - 6
2y = 3x - 8
y = ³/₂x - 4
