Answer:
General conditions of congruency of triangles
Step-by-step explanation:
As no triangles are given, explaining the general rules to apply in congruency of all triangles.
Triangles are congruent on the basis of following conditions :
- SSS : All 3 sides of two triangles are equal
- SAS : 2 sides & angle between them, of two triangles are equal
- ASA : 2 angles & corresponding side, of two triangles are equal
- HL : Hypotenuse & Leg of two right angled triangles are equal
Answer:
this is your answer. thanks!!
The answer is 16. Spinning an even number and flipping tails
3 - 2a > 7
We need to solve for a
First, let's subtract 3 on both sides to have the variables on a side and the numbers on another side:
3 - 2a > 7
3 - 2a - 3 > 7 - 3
- 2a > 4
Let's divide both sides by -2 to have a on side and its value on the other side:
-2a > 4
(-2a)/(-2) > (4/-2)
a < -2 (In a case of an inequality, we change the sign when we divide by a negative number to its opposite).
So 3 - 2a > 7 when a < -2 (answer c)
Hope this helps! :D
