Parenthesis first
-(-16) = 16
24+ 16 +(-1/2)x = 18-(-8)
+(-1/2)x
-1/2x
24 +16 -1/2x = 18-(-8)
-(-8) = 8
24+ 16 - 1/2x = 18 + 8
24+ 16 = 40
18+8 = 26
40 - 1/2x = 26
-40 -40
-1/2x = -14
(-2) -1/2x = (-2)-14
x = 28
By using what we know about intersecting lines, we will see that:
- a) ∡7 = 47°
- b) 47° + (2x - 5)° = 180°
- c) x = 69
<h3>
How to get the measures of the angles for two intersecting lines?</h3>
When two lines intersect, 4 angles are formed. There are two properties that these angles have.
- If the angles are adjacent, then their measures add up to 180°
- If the angles are not adjacent, these angles have the same measure.
a) We know that ∡5 = 47°
And 7 is not adjacent to 5, then 7 has the same measure:
∡7 = 47°
b) 6 and 5 are adjacent, then we must have that:
∡5 + ∡6 = 180°
47° + (2x - 5)° = 180°
That is the equation we need to solve to get the value of x.
c) To solve the linear equation we need to isolate x, let's do that:
47° + (2x - 5)° = 180°
(2x - 5)° = 180° - 47° = 133°
2x - 5 = 133
2x = 133 + 5 = 138
x = 138/2 = 69.
