The gfc of 24 and 30 is 6.
Answer:
AD ≅ CD.
Step-by-step explanation:
Statement : consider triangles ADB and DBC.
1) AB = CD
2) ∠ABD = ∠DBC
3) DB = DB
4) ⇒ ΔADB and ΔDBC are congruent triangles.
5) AD = DC.
Reasons ;
1) given, AB = CB
2) given, DB bisects ∠ ABC
3) common side of both triangles
4) as two sides and one angle are equal in both triangles
5) congruent triangles
The 4th roots of a^12 = a^3 so we can take out a^3
4th root of 144 = 4th root of 9 * 2 so we can also take out 2
The answer is the first choice.
40 + 12x = 100
subtract 40 from both sides
12x = 60
divide by 12 on each side
x = 5

The obtuse interior angle in triangle can reach to 179.9999999.... °.
Because once it hits 180°, the angle becomes a straight line and it is not possible in a triangle.
