Answer:

a=127

Step-by-step explanation:

Okay so basically thats a straight line that the angles are on right? Yes so that entire angle is equal to 180 so you set up the equation 15+38+a=180 and then you simplify which is 53+a=180, then you subtract 52 from both sides and you get a=127. Hope this helps :)

What is the distance from the point (a, −b, −4) to the origin?

laiz [17]

Answer:

$\sqrt{a^2+b^2+16}$

Step-by-step explanation:

The distance (d) between two points in 3 dimensions is ...

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)

Then the distance between (a, -b, -4) and (0, 0, 0) is ...

d = √((a -0)² +(-b -0)² +(-4 -0)²)

= √(a² +b² +16)
