Find the sine of angle Z.
1. four fifths

2. two fifths

3. five halves

4. five fourths

1 - four fifths (4/5)

Step-by-step explanation:

Sine=opposite/hypotenuse

Thus, from angle z, sinz=8/10=4/5, so the answer is choice 1

You have said that Brigitte is shorter than 5 feet. Translating your statement into rigorous mathematical terminology, we would write "Brigitte's height is less than 5 feet.". Then, using 'h' to represent Brigitte's height, and '<' to represent the words "less than", we can write the statement symbolically as [ h < 5 feet ].
