Answer:
your answer is the second option
Step-by-step explanation:
Step-by-step explanation:
for some reason the equation at the top says 7(x+2) but both of the equations at the bottom say 7(x-2)... I'm just going to do 7(x-2)
Emmanuels Work:
7(x-2)=91
distribute the 7 by multiplying both x and -2 by it
7x-14=91
add 14 to both sides
7x=105
divide both sides by 7
x=15
Mauricio's Work:
7(x-2)=91
to get rid of the 7 multiplication, divide both sides by 7
x-2=13
add 2 to both sides
x=15
Angle1 + angle2 = 180°(because they are a linear pair)
or, (x-36) + (x+84) = 180
or, x - 36 + x + 84 = 180
or, 2x + 48 = 180
or, 2x = 180 - 48
or, 2x = 132
or, x = 132/2
therefore, x = 66
angle1 = (x - 36) = 66-36 = 30°
angle2 = (x+84) = 66+ 84 =150°
Answer:
<P = 27°
Step-by-step explanation:
In a triangle, the sum of all three interior angles = 180
So triangle NOP, <N + <O + <P = 180
Plug in
9x - 1 + 3x - 2 + 2x + 1 = 180
14x = 2 = 180
14x = 182
x = 13
<P = 2x + 1
<P = 2(13) + 1
<P = 26 + 1
<P = 27
Answer:
<P = 27°
