Answer:
It should be D and E
Step-by-step explanation:
I hope that helps
Use the Pythagoras Theorem:-
5^2 = x^2 + 3^2
x^2 = 5^2 - 3^2 = 16
x = sqrt 16 =4 feet Answer
Answer:
The second option is the answer.
Step-by-step explanation:
The center of a dilation makes all the corresponding vertices coincide at one point if we draw a straight line including that pre image and new image point. All coordinates correspond about Point C. So the first two options are the viable answers.
The blue triangles right side measure is 10 while the smaller triangle right side measure is 5. This means the scale factor is
So our scale factor is 2.
The second option is the answer.
Area of triangle is 1/2 times base times height
lets say the base is from x1,y2 to x1,y1 the distance is 6 units
1/2 times 6 times height
from x1,y1 to x3,y3 is 7 units to the right
1/2 times 6 times 7=3 itmes 7=21
area=21 square units or
21 units^2
Answer:
point (-2,11) does not lie on the given line
Step-by-step explanation:
To find : Which of the following points does not lie on the line ?
Solution :
To determine the point lie on line or not we have to put points in equation if it satisfy then it lie otherwise not.
a) Point (1,8)
Line y=3x+5
Substitute x=1 and y=8
8=3(1)+5
8=8
(1,8) point lie on the line.
b) Point (4,12)
Line y=3x+5
Substitute x=4 and y=17,
17=3(4)+5
17=12+5
17=17
(4,17) point does not lie on the line.
c) point (-2,11)
Line y=3x+5
substitute x=-2 and y=11
11=3(-2)+5
11=-6+5
11 is not equal to -1
d) Point(0.5)
Line y=3x+5
Substitute x=0 and y=5
5=3(0)+5
5=5
