Angie’s rotation maps triangle XYZ to triangle X’Y’Z’. X(3, –6) maps to X’(–3, 6)
Y(1, –2) maps to Y’(–1, 2)
Z(–1, –5) maps to Z’(1, 5)

Which describes the rotation?
180 degrees rotation
270 degrees clockwise rotation
90 degrees counterclockwise rotation
90 degrees clockwise rotation

Step-by-step explanation:

The described is the rule:

This is the 180 degrees rotation

Correct option is A.

Theory

When the coordinates (x,y) of the triangle is rotated 180°, the new coordinates become (-x,-y).

Angle’s rotation maps triangle XYZ to triangle X’Y’Z’.

X(3, –6) maps to X’(–3, 6)

Y(1, –2) maps to Y’(–1, 2)

Z(–1, –5) maps to Z’(1, 5)

Which describes the rotation?

180 degrees rotation ✓

270 degrees clockwise rotation

90 degrees counterclockwise rotation

90 degrees clockwise rotation

180° degree rotation is the right answer.

what's that

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
