Answer:

I call this angle chasing or angle hunting. The answer is 60°.

Step-by-step explanation:

m \: bad = 25 \\ m \: bcd = 70 \: therefore \\ m \: adc \:  = 180 - (70 + 25) = 85

since ∆ BAD is an isosceles triangle m BDA = m BAD = 25°

m \: adc \:  - m \: adb = 85 - 25 = 60 \\ x = 60 \: degrees

Suppose two triangles are similar and one pair of sides of the triangles are congruent. Are the triangles necessarily congruent?
vladimir1956 [14]

Answer:

Yes. For the triangles to be similar, all of the sides have to be proportionate to its corresponding side. If the ratio of one of the pairs sides of the triangles is 1:1, then all of the pairs of sides on the triangles have to also have a ratio of 1:1. Using this, according to SSS postulate, the two triangles are similar. With the given information, either both triangles are congruent, or they are not similar.

someone help me please for 12 points!!! the first five steps of a pattern are shown, what are the next three steps in the patter
prisoha [69]

The -9 stays the same the whole time but the other number being multiplied decreases by one each layer, so the next three would be:

-9 x -1 = 9

^^^ -1 is in the second multiplication slot bc 0 - 1 = -1

-9 x -2 = 18

^^^ -2 is in the second multiplication slot bc 0 - 2= -2

-9 x -3 = 27

^^^ -3 is in the second multiplication slot bc 0 - 3 = -3

***Remember that when you are multiplying two negative numbers the solution will be positive

Hope this helped!
