Answer:
x= -2
Step-by-step explanation:
set the two equations equal to each other, and since the x2 cancels out, you're left with 3x+2= 2x, which simplifies to x= -2
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.

If nine plus 10 is 21 and the square root of the sun is blank
To make a congruent segment using a compass and a straight edge you need to get your compass and find the Distance between the two points, Then without changing the measurement copy it to a line. The straight edge would be used to make a line.
I hope this helps!
