Answer:

x = 30 degrees

Step-by-step explanation:

Those are complementary angles, which means they add up to 90 degrees

2x + x is 3x

To find x you have to divide 90 by 3

x equals 30

2x = is 60

Hope this helps :)

Answer:

the 19th term of the arithmetic sequence is 73.

Step-by-step explanation:

Given:

The arithmetic sequence whose common difference is

$d=4$

And first term is

$a=1$

Find the 19th term of the arithmetic sequence

$n=19$

Now we know that,

$a_{n}=a+(n-1)d$

Put all the value in above AP.

$a_{19}= 1+(19-1)4$

$a_{19}= 1+18\times 4$

$a_{19}= 1+72$

$a_{19}= 73$

So, $19_{th}$ term of the sequence is 73.

Find the distance between the points (-4,5), (-12,5)

posledela

Answer:

d = 8

Step-by-step explanation:

For:

(X1, Y1) = (-4, 5)

(X2, Y2) = (-12, 5)

Distance Equation Solution:

d=(−12−(−4))2+(5−5)2−−−−−−−−−−−−−−−−−−−−√

d=(−8)2+(0)2−−−−−−−−−−√

d=64+0−−−−−√

d=6–√4

d=8

Therefore, the distance between (-4,5), (-12,5) is 8.
