Answer:

X=18

Step-by-step explanation:

Pentagon = 540 degrees total

Find Known Angel total:

95+ 90= 185

subtract from 540:

540-185=355

add all unknown angles together:

(7x-4)+ (3x+23)+(9x-6)= 19x+13

set up equation and solve

19x+13=355

19x=355-13

19x= 342

x=342/19

x=18

Answer:

$1,075

Step-by-step explanation:

Simple Intereat Formula:

A = P(1+rt)

where A is the final amount,

P is the principal(original amount invested)

r = annual interest rate

t = time in years

Given P = 1000

r = 2.5/100

t = 3 (Beginning of 4th year means the 4th year is not counted)

A = 1000(1+(0.025)(3))

= 1000(1.075)

=$1,075

The first term of an arithmetic sequence is -5, and the tenth term is 13. Find the common difference.
Novay_Z [31]

Working
The nth term of an arithmetic series is calculated using the formula
nth term= a+ (n-1) d
a= -5, n =10 and nth term in this case is 13
Thus
13= -5 +(10-1)d
13= -5+9d
9d= 18
d = 2

PLEASE HELP!! Find the missing side and round to the nearest tenth.
yawa3891 [41]

Answer:

Hey there!

We have an angle of 51 degrees, and a hypotenuse of 16 units in length.

Thus, because the missing side is adjacent to 51 degrees, we can use Cosine 51= x/16, or Cosine 51 (16)=x=10.01

x=10.0 units.
