The size of the fourth angel = 360 - ( 53 + 127 + 72 ) = 108
Answer:
1) 6x+3y=5
Step-by-step explanation:
1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula 
. Substitute the x and y values of the two points into the formula and solve:
So, the slope is -2.
2) Now, identify the slopes of the lines in the options. We already know the slope of 
is 
since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.
To find the slope of 
, isolate y to put the equations into slope-intercept form (
format), and whatever the coefficient of the x-term is will be the slope.
.
So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.
Answer:w = -5/4
Step-by-step explanation:
Answer:
y=22/3
x=53/3
Step-by-step explanation:
the first number is x
second number is y
x=2y+3
x+y=25
and solve system of equation
so
x=-y+25
-y+25=2y+3
3y=22
y=22/3
x=53/3
