State the hypotenuse, opposite and
adiacent sides in the triangle ABD
in the previous frame if 60degree is the
reference angle.

hypotenuse:2 (AB)

adjacent side: 1 (AD)

opposite side:√3(BD)

Step-by-step explanation:

-->AB is hypotenuse cuz it's opposite to right angle (90°)

-->AD is adjacent,cuz it's adjacent to reference angle(60°)

-->BD is opposite side,cuz it's opposite to the reference angle(60°)

✌️:)

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
