Sorry wish I could help but I need to see the picture to answer the question. Sorry :-(
Answer:
11 and 12
Step-by-step explanation:
x=smaller
y=larger
2y=3x-9 x+1=y
2(x+1)=3x-9
2x+2=3x-9
11=x
11+1=y
12=y
Answer:
EH = 9.4
Step-by-step explanation:
A rhombus is a quadrilateral with equal length of sides.
Given that, EF = 13 and DF = 18
⇒ DH = HF = 
= 9
The property that the diagonals of a rhombus are at right angle to each other.
Thus, applying the Pythagoras theorem, we have;
=
+ 
=
+ 
=
+ 
169 =
+ 81
= 169 - 81
= 88
EH = 
= 9.381
The length EH is 9.4
Answer:
Rotated at 90° clockwise about the origin. (RO 90)
Step-by-step explanation:
According to the statement A(–3, 4) maps to A'(4, 3), B(4, –5) maps to B'(–5, –4), and C(1, 6) maps to C'(6, –1). That is to say, that a point in the form P(x, y) maps to P(y, -x) after rotation.
In that sense, if a point P(x, y) maps to P(y, -x) then this happens when the shape denoted by those three points is rotated at 90° clockwise about the origin.
