Points M and N are both on ZB with M between Z and N. ZM = 10
maxonik [38]

Answer:

Your answer is 40%

Step-by-step explanation:

It is 20 units between Z and B.

We add 2 more points, and one of them is at the the halfway point of the entire line.(M)

One of them is only 2 units away from B.(N)

That means our line is halved, so from 20/20 possible places a point could go and land in the right area is now 10/20.

Minus 2 from that; to take into count of the N to B, and you have 8/20

8/20 is just 40%

In ABC , <br> a = 3, c = 19<br> A. m
nata0808 [166]
We will use the Pythagorean theorem:
b² = 19² - 3² = 361 - 9 = 352
b = √352 = 18.76 ≈ 18.8
sin A = 3 / 19 = 0.15789
m ∠ A = sin ^(-1) 0.15789 = 9.08° ≈ 9.1°
m ∠ B = 90° - 9.1° = 80.9°
Answer:
A ) m∠ A = 9.1°,  m∠B = 80.9°,  b = 18.8
