Answer:

Step-by-step explanation:
We can use a couple of angle relationships to find the missing angle.
1. All angles in a triangle add up to 180°
We know that all angle in a triangle will add up to 180°. Since we know the measure of 2, we can find the other angle easily.

So the other angle in the triangle is 50°.
2. The 50° angle and the missing angle are supplementary.
We know that the missing angle and the third triangle angle are supplementary. This means that their angle measures will add up to 180°.
Since we know one, we can find the measure of the other.

So the missing angle is 130°.

Answer:
I think the answer is D because you cant find the other measures unless you have at least one angle measure but you don't so you cant determine the answer.
Step-by-step explanation:
You mean 60%of 5 1/2? that makes more sense...
i would do it like this:

(60% is the same as

(so that there is no confusion, i've put it into an improper fraction
now we can multiply:





which is 3.3.
so 60% of 5 and a half is 3.3.
Answer:
D) (-2, -3)(-4, -3)(-2, -9); because corresponding pairs of sides and corresponding pairs of angles are congruent
Step-by-step explanation:
For triangles to be congruent, it is not enough that corresponding angles are congruent. In addition, there must be at least one pair of corresponding sides that are congruent. (Then all pairs will be congruent.)
The points listed in choices B and D are points that form a right triangle with leg lengths 2 and 6. However, choice B only refers to the angle measures, and not the sides. Choice D is the correct one.
