Answer: B
Step-by-step explanation:
Answer:
- 4/15
Step-by-step explanation:
Just take 4 and 15 make that a fraction make the fraction a negative not the 15 because they will be the same thing no matter where you place it
Answer:
Yes they are similar.
There are three similarity criteria for triangles.
The first one (AAA) , your case, says that two triangles are similar if their corresponding angles are equal.
The second one (SAS) says that two triangles are similar if two sides have lengths in the same ratio and the angles that are included in these two sides are equal.
The third one (SSS) says that two triangles are similar of all of their sides have lengths in the same ratio.
About the first criteria, you actually need only two corresponding angles to be the same, because the third will always be the difference between 180° and the two angles.
Remember that you CANNOT exceed 180° for the sum of the three angles of a triangle.
And remember also that similarity involves correspondence in sides and angles. Two triangles, with same angles, but mirrored, are not similar!
The first 3 , after 2 and 6
Answer:
B or 108
Step-by-step explanation:
we know that the line splits the 90 angle, so the other side is 54
Since it is a isosceles triangle, the base angles are the same and they are both 54 degrees.
The sum of all the angles in a triangle is 180, so 180-54-54 is 72.
Since the line intersecting the triangle is a straight angle 180, we do 180-72=108
