Answer:

The answer is A, the measure of angle Z is 45°.

Step-by-step explanation: According to base angle theorem for iscoscles triangles, the base angles must be the same angle measure if the sides opposite to them are congruent. Since it is an iscoceles triangle, they are automatically congruent. This means that Y is 90 degrees. This fits into triangle sum theorem because if Z is 45 degrees, than x is also 45 degrees making a viable triangle. This means that this is the only one that actually applies. B is wrong because of triangle sum theorem, C is wrong because of triangle sum theorem, and D is wrong because of the SSS postulate and CPCTC.

A triangle has coordinates A(6,1), B(6,5), and C(4,1). If the triangle is rotated 180 degrees, what are the new coordinates of t
4vir4ik [10]

Answer:

A(-6,-1) B(-6, -5) C(-4, -1)

Step-by-step explanation:

When a coordinate is rotated 180 degrees, they go from (x,y) to (-x,-y), so all you need to do is multiply every coordinate by -1

P-24=15

because if argentina has 15 more than south africa then you need to subtract 24-15=p which is pretty much the same things as p-24=15
