Get rid of cos2x by dividing both the values. So Sin2x/cos2x +3cos2x/cos2x.
Tan2x = 3
2x = -71.5 so x is -35.6
Use the quadrant method and add 360 twho the two values tou get.
Answer:
Yes, they are congruent.
Step-by-step explanation:
Congruent segments are segments whose lengths are equal.
You plotting of the points is correct.
Now look at the length of each segment.
Points R and S are both on the same horizontal line since their y-coordinates are both equal, 7. The distance from 3 to 6 is 3, so the length of segment RS is 3.
Points T and U are both on the same vertical line since their x-coordinates are both equal, 5. The distance from -3 to 0 is 3, so the length of segment TU is 3.
The lengths of segments RS and TU are both 3, which makes them equal. That makes the segments congruent.
Answer: Yes, they are congruent.
Scalene triangle is a triangle with no congruent sides
isosceles triangle is a triangle with at least 2 congruent sides (i.e. 2 or 3 congruent sides)
equilateral triangle is a triangle with exactly 3 congruent sides.
Graph 15 is an isosceles triangle
