Answer: 48°

Step-by-step explanation: AD=AB, ∠ADC=∠ABC.

(5x-147)°=2x°, 3x=147, x=49.

So, ∠ADC=∠ABC=98°,

∠DCB=360°-{116°+2(98°)}

=360°-(116°+196°)

=360°-312°

=48°

What is the solution to the inequality 2n+5| &gt; 1?
hodyreva [135]

Answer:

n < - 3 or n > - 2

Step-by-step explanation:

Inequalities of the type | x | > a , have solutions of the form

x < - a or x > a

Then

2n + 5 < - 1 or 2n + 5 > 1

Solve both inequalities

2n + 5 < - 1 ( subtract 5 from both sides )

2n < - 6 ( divide both sides by 2 )

n < - 3

OR

2n + 5 > 1 ( subtract 5 from both sides )

2n > - 4 ( divide both sides by 2 )

n > - 2

Solution is n < - 3 or n > - 2
