Step-by-step explanation:
X + y = 120(being alternate angle)
or,X=120-y
then
2x-y=120
or,2(120-y) - y= 120
240-2y-y=120
y=240-120
y= 120
again,
X=120-y
= 120-120
=0
hence,
X= 0
y= 120
Answer:
1. 110
2. 70
3. 70
4. 110
5. 110
6. 70
7. 70
Step-by-step explanation:
when to lines cross, opposite angles are equal so like 1 and 4 are equal
1, 4, and 5 are equal to 110
to find 2, 3, 6, and 7, subtract 110 from 180
Answer:
AB = 9
Step-by-step explanation:
The perpendicular bisector divides Δ ABC into 2 congruent triangles, that is
Δ ABD ≅ Δ ACD , then
AB = AC = 9
One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.
