Which points are exactly 10 units from the point (–8, –2)? Check ALL that apply.

Archy [21]

Answer:

The points that are exactly 10 units from the point (–8, –2) are (2, –2) and (–8, 8).

Step-by-step explanation:

The distance formula is;

d= $\sqrt{( x_{2}-x_{1} )^{2}-(y_{2} -y_{1} )^{2} }$

So for distance between: (–8, –2) and (2, –2) is:

d= $\sqrt{( 2-(-8))^{2}-(-2 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Similarly for distance between: (–8, –2) and (–8, 8) is,

d= $\sqrt{( -8-(-8))^{2}-(8 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Find the value of this pronumeral

Rina8888 [55]

Answer:

x = 70 ;

y = 50 .
_____________________________________________________
Explanation:
_____________________________________________________
y = 50 ; since vertical angles are congruent.

180 – (50 + 60) = x ; since all angles in any triangle add up to 180 degrees.

↔ x = 180 – (50 + 60) = 180 – (110) = 70.
