Answer:
120°
Step-by-step explanation:
18/25, 51/75, 33/50, 13/20, 3/5
-5=1+x/3
Subtract 1 from both sides
-6=x/3
Multiply both sides by 3
-18=x
Check:
1+ -18/3=1-6=-5. Works!
So the answer is x= -18

Step-by-step explanation:
Enlarge the triangle ABC by a scale factor of 2 about the centre of enlargement O.
First, draw ray lines from O to each corner of the triangle and extend them.
Next, measure the distance from O to each corner of ABC. ...
Finally, join up the points A' B' C'
Locate the Centre of Enlargement, then draw Ray Lines from the centre of enlargement through the vertices of the shape. If a shape is being enlarged by a scale factor of 2, the distance from the centre of enlargement to each vertex will be twice the size. The size of the shape will also be twice the size.
Answer:
9
Step-by-step explanation:
Missing point will be represented by X
(5+8+7+11+X)/5 = 8
Multiply 5 to get rid of and...
5+8+7+11+X = 40
Simplify
31+X = 40
Subtract
X=9
