Answer:

The answer is the first one ⇒ AAS

Step-by-step explanation:

∵ DB ⊥ AC

∴ m∠DBA = m∠DBC = 90° ⇒ (1)

∵ m∠A = m∠C ⇒ (2) given (from figure)

∵ DB is a common side in the two Δ ⇒ (3)

From (1) , (2) and (3)

∴ Δ ABD is congruent to Δ CBD ⇒ AAS

Help cause I haven’t been paying attention in class hehehe

Answer:

1) g ≥ 17

2) g > -10

3) g > -1

Step-by-step explanation:

1) 7 (g-19) ≥ -14  divide both sides by 7

g - 19 ≥ -2          add 19 to both sides

∴ g ≥ 17

=======================================

2)   3(7g+17) > -19 + 14g

21g + 51 > -19 + 14g

21g - 14g> -19 - 51

7g > -70

g > -10

========================================

6(-6g+6) > -2(19g-17)

-36g + 36 > -38g + 34

-36g + 38g > 34 - 36

2g > -2

g > -1

========================================

The lengths of the sides of a triangle are 9​, 12​, and 18. Classify the triangle as​ acute, right, or obtuse.
Nataliya [291]

Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Assign the largest value to 'c'

If a² + b² = c² , then it is right triangle

If a² + b² > c², then it si acute triangle

If a² + b² < c² , then it is obtuse triangle

Here, a = 9 , b = 12 & c = 18

a² + b² = 9² + 12²

           = 81 + 144

a² + b² = 225

c² = 18²

c² = 324

a² + b² < c²

225 < 324

So, 9, 12 , 18 form a obtuse triangle
