Answer:
"Rotation" means turning around a center: The distance from the center to any point on the shape stays the same.Every point makes a circle around the centre.
The Figure 2 was constructed using figure 1.Among all the given options those which apply for the transformation to be defined as a rotation are :
A)The segment connecting the center of rotation, C, to a point on the pre-image (figure 1) is equal in length to the segment that connects the center of rotation to its corresponding point on the image (figure 2)
(B)The transformation is rigid.
(C)Every point on figure 1 moves through the same angle of rotation about the center of rotation, C, to create figure 2.
(E)If figure 1 is rotated 360° about point C, it will be mapped onto itself.
Options A,B,C,E are the correct ones.
Answer:
B. m∠RTS = 78°
Step-by-step explanation:
The sides GH and GI of ΔGHI have the same length, so their opposite angles, ∠I and ∠H will have the same measures. Call that measure "x".
The sum of angles in a triangle is 180°, so we have ...
24° +x +x = 180°
2x = 156° . . . . subtract 24°
x = 78° . . . . . . divide by 2
The triangle similarity statement tells you that ∠T will have the same measure as ∠I, which is x, or 78°.
m∠RTS = 78°
Answer:
D
Step-by-step explanation:
Use the distance formula to find the radius of the circle.
This implies that:
From the diagram;
Also;
The central angle of the shaded region is
The area of the shaded region is
Answer: 9/20
Step-by-step explanation:
From the question, we are informed that Tyce hit 3/5 of the baseballs pitched to him during batting practice and that Mason hit 3/4 of the number of the pitched that tyce hit.
The fraction of pitches that Mason hit will be gotten by multiplying 3/4 by 3/5 This will be:
= 3/4 × 3/5
= 9/20
It is 60 because 51+9 is 60
