Answer:

$x + 1 + x + 3 = 180$

by vertically opposite angle theorem

$x + x + 1 + 3 = 180$

$2x + 4 = 180$

$2x = 180 - 4 = 176$

$x = \frac{176}{2}$

$x = 88$

have a nice day

Find the average value of the following numbers 87, 79, 84, 70, 90

dem82 [27]

Explanation

the average is calculated by dividing the sum of the values in the set by their number.

Step 1

Let

$\begin{gathered} \text{set}=\lbrace87,79,84,70,90\rbrace \\ the\text{ sum of the values is=87+79+84+70+90}=410 \\ n\text{umber of values= 5} \end{gathered}$

Step 2

apply the equation

$\text{Average}=\text{ }\frac{the\text{ sum of the values}}{\nu mber\text{ of values}}=\frac{410}{5}=82$

so, the answer is 82

Sydney is playing a game on a map with a marked grid. To start, she places a game piece at (1, 4). She moves 3 units east and 2

Anastasy [175]

Answer:

(7, 8)

Step-by-step explanation:

If Sidney places each piece 3 units east and 2 units north of the last one, we can figure out which coordinate comes first by subtracting the position of the second piece (S) by the position of the first piece (F):

$S - F = (4,6) - (1,4) = (3,2)$

We can conclude that coordinates are in the (East, North) format.

Therefore, the location of the third piece (T) is:

$T = S(E,N) +(3,2)= (4,6)+(3,2)\\T = (7,8)$
