Find the measure of the indicated angle
Answer:
? = 110
Step-by-step explanation:
We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.
All angles of a triangle always adds up to 180
Add all the known angles 25 + 45 = 70
Than subtract 180 - 70 = 110

A parallelogram is formed by the points A (2, 4), B (6, 3), C (0, 0), and D (4, 1). What transformation could have occurred in order for A’ to be (3, 6)? A. Dilation of 150% B. Reflection across the axis y=5 C. Rotation of 90° about the origin D.Translation following the rule (x+2,y+1)
Answer:
c please give me brainliest
Step-by-step explanation:
The dilation of 150% from A(2, 4) to A'(3, 6). Therefore, option A is the correct answer.
Given that, a parallelogram is formed by the points A (2, 4), B (6, 3), C (0, 0), and D (4, 1).
What is the transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
The coordinates of the point A' is (3, 6)
Now, 150% of (2, 4) is 0.15 × 2 = 3 and 0.15 × 4 = 6
So, its dilation of 150% from A(2, 4) to A'(3, 6)
The dilation of 150% from A(2, 4) to A'(3, 6). Therefore, option A is the correct answer.
