Answer:
0.7 is the decimal expansion okok
Step-by-step explanation:
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.

Answer:
Step-by-step explanation:
Slope is 2
solve into Ax+by=C
Y-y1=m(x-x1)
Y-(-4) = 2(x - (-5))
Y+4=2x+10
Y-2x =6
(0,6)
(-3,0)
Answer:
probably 4 times since it is not 100% accurate I guess
Answer:
Area of triangle = 1/2*b*h
= 1/2*10*4.5
= 1/2*45
= 45/2
= 22.5
