Find the missing angle for each triangle below and state the tool you used to find the angle.

19.2 degrees using sine rule

Step-by-step explanation:

right angle = 90 degrees

to find the missing angle, we use the sine rule

insert the values that you have:

cross multiply

use inverse sine to get the angle

19.2 degrees

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
