Answer: x=27
Step-by-step explanation:
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
D=rt
120= r(3)
120/3=3r/3
40=r
Answer:
x = 17
<2 = 121
Step-by-step explanation:
We know that angle 1 and angle 3 form a linear pair, which means they add to 180
7x+2 + 3x+8 = 180
Combine like terms
10x+ 10 = 180
Subtract 10 from each side
10x+10-10 = 180-10
10x = 170
Divide by 10
10x/10 =170/10
x = 17
Angle 1 and angle 2 are vertical angles and vertical angles are equal
<1 = <2 = 7x+2 = 7(17) +2 =119+2=121
