Answer:
y = 4
Step-by-step explanation:
If you have moved z from -1 to +1, you have moved it +2 (2 to the right). If you move z from 5 to 1 you have moved it down 4. So your rule here in coordinate form is (+2, -4). Add 2 to each of the other x coordinates and subtract 4 from each of the other y coordinates to get the new points. A(3, -1) P(0, 0) Z(1, 1)
You just have to look at the table that give you it was angle 31 so then you would go to angle and go across the line to where it says cos then you right the number which would be 0.8572
Answer:
Step-by-step explanation:
Top triangle:
The hash marks indicate congruence. So, x is congruent to 15 or x= 15
x+6= 21
The length of the sides of this triangle are 15,15, and 21.
Two sides are congruent so isosceles.
Bottom triangle:
The sum of the angles in a triangle is 180.
30+35+x=180
75+x=180
x=105
105> 90, so this is an obtuse triangle.
Answer:
Step-by-step explanation:
- ED = FG = 4, easy to calculate
- ED ║ FG, both are vertical line segments
- EF ║ DG as the slopes are same
- m(EF) = (7-6)/(6-1) = 1/5
- m(DG) = (3-2)/(6-1) = 1/5
As we see the opposite sides are parallel and congruent. This is the property of a parallelogram
