In an arithmetic sequence, the nth term an is given by the formula An=a1+(n−1)d, where a1is the first term and d is the common

Olin [163]

Answer: 433

Step-by-step explanation:

The given sequence : 19,42,65,88,...

We can see that the terms ha common difference as :-

$42-19=23\\65-42=23\\88-65=23$

Thus, its an Arithmetic progression with common difference (d)=23

The formula to find the nth term is :-

$a_n=a_1+(n-1)d$

Now, the 19th term of the given sequence :-

$a_{19}=19+(19-1)(23)\\\\=19+(18)(23)\\\\=19+414=433$

Hence, the 19th term of 19,42,65,88,... is 433.

If mJI = (3x+2)°, mHLK = (15x-36)°, and m∠HML = (8x-1)°, find mHLK

Gala2k [10]

Answer:

The value of mHLK will be "(204)°".

Step-by-step explanation:

The given values are:

mJI = (3x+2)°

mHLK = (15x-36)°

and,

m∠HML = (8x-1)°

then,

mHLK = ?

Now,

By using chord-chord formula of angle, we get

$mHMK=\frac{1}{2}(mJL+mHLK)$

On putting the values in the above formula, we get

⇒ $(8x-1)=\frac{1}{2}(15x-36+3x+2)$

On applying cross-multiplication, we get

⇒ $2(8x-1)=18x-34$

⇒ $16x-2=18x-34$

On subtracting "18x" from both sides, we get

⇒ $16x-2-18x=18x-34-18x$

⇒ $-2x-2=-34$

On adding "2" both sides, we get

⇒ $-2x=-34+2$

⇒ $-2x=-32$

⇒ $x=\frac{32}{2}$

⇒ $x=16$

On putting the value of "x" in mHLK = (15x-36)°, we get

⇒ (15x-36)° = (15×16-36)°

⇒ = (240-36)°

⇒ = (204)°

So that mHLK = (204)°
