What do u mean I’ll answer I just don’t understand wht u mean
Answer:
(x+1)+(3x+1)+(2x+4)=180 (sum od all sode of a triangle is 180)
x+1+3x+1+2x+4=180
6x+6=180
6x=180-6
x=174/6
x=66
Answer:
The equation in the standard form of the line through the given points is;
y = 3x - 17
Step-by-step explanation:
We start by getting the slope of the line;
m = (y2-y1)/(x2-x1)
m = (7-10)/(8-9) = -3/-1 = 3
The stands equation form is;
y = mx + b
m is slope, b is the y-intercept
so we have
y = 3x + b
To get b, we substitute the coordinates of any of the points
10 = 3(9) + b
10 = 27 + b
b = 10-27
b = -17
So the equation is;
y = 3x - 17
Answer:
Step-by-step explanation:
<1=180°-74° so <1=126°
<2=180°-90° so <2=90°
<3=180°-116° so <3=64°
<4=180°-65° so <4=115°
by using 
° =(3)180°/5 -<1 -<2 -<3 -<4 =<5
you find out the last.
