Answer:
when P(x,y) is reflected in y=x line then
P(x,y) = P(y,x)
A(2, -1)= A(-1, 2)
B(-2, -1) = B(-1, -2)
C(2, 1)= C(1, 2)
D(1,2)= D(2,1)
Step-by-step explanation:
Dang that’s hard , hope somebody helps you.
Given:
Consider the completer question is "If ∆BTS≅∆GHD, BS=25, TS=14, BT=31, GD=4x-11, m∠S=56, m∠B=21 and m∠H=(7y+5), find the values of x and y.
To find:
The values of x and y.
Solution:
We have,
(Given)
(CPCTC)
Divide both sides by 4.
In ∆BTS,
(Angle sum property)
Now,
(CPCTC)
Divide both sides by 7.
Therefore, the value of x is 9 and value of y is 14.
Step-by-step explanation:
okay so -25 • -9 = 9+10
225 = 9+10
225 = 19
19. 19
= 11.8
Answer:
C. 70 cm
Step-by-step explanation:
Split all the shapes, so, the square would be:
4 × 10 = 40
---------------------------------------------------------------------------------------------------------------
Each triangle has an area of 7.5:
7.5 × 4 = 30
---------------------------------------------------------------------------------------------------------------
30 + 40 = 70
---------------------------------------------------------------------------------------------------------------
Have a good day :)
