Answer:
x=4, y=3 (4,3)
Step-by-step explanation:
- x=7−y
19+y=22
y=3
-Substitute y=3y=3 into x=7-yx=7−y.
x=4
Two sides are equal in an isosceles triangle. This means that the angle both sides make with the third side must be the same. Since the angles in a triangle add up to 180°, you can subtract 110° from 180° and divide your answer by two. The resulting number will be the measure of each of the two unknown angles
Answer:
#3
Step-by-step explanation:
(x,y) (x,y,+1)
Sure but where is the test?
The image of the point (x, y) by R (90, O) is (-y, x)
Point R = (1, -1), then
Point R' = (1, 1)
Point S = (4, 1), then
Point S' = (-1, 4)
Point T = (4, -3), then
Point T' = (3, 4)
The answer is D
