Answer: 5√2
Let’s say A(-5,-3) and B(2,-4)
AB= sqr (xB-xA)² + (yb-yA)²
= sqr [2-(-5)]² + [-4-(-3)]²
= sqr 49 + 1
= sqr 50
AB= 5 sqr 2
(sqr=square root)
Answer:
x = 18
Step-by-step explanation:
5/6x = 15
Multiply each side by 6/5 to isolate x
6/5 * 5/6 x = 15 *6/5
x = 15/5 *6
x =3*6
x = 18

I don’t have an explanation, I am really bad at those
Hope this sort of helps!
Let the second angle = X
The first angle = 2X+42 ( 42 more than 2 times the second angle)
Now you have 2x+42 + x = 90 ( first angle + second angle = 90)
2x + x = 3x
Now you have:
3x +42 = 90
Subtract 42 from both sides:
3x = 48
Divide both sides by 3:
x= 48/3
x = 16
The second angle = 16 degrees.
The first angle = 2(16) + 42 = 32+42 = 74 degrees
