Step-by-step explanation:
3.0
Answer:
Use trigonometric ratio
Step-by-step explanation:
Since it is one side and angle of the triangle that is given, it is assumed that the triangle is a right-angled triangle
To solve for one of the two unknown lengths, use trigonometric ratio
There are 3 basic trigonometric ratio namely Sine (sin), Cosine (cos) and Tangent (tan)
Sine of the angle given = opposite side ÷ hypotenuse side
Cosine of the angle given = adjacent side ÷ hypotenuse side
Tangent of the angle given = opposite side ÷ adjacent side
Assuming the length given is the hypotenuse side and the angle is inclined to the horizontal
To find the opposite side of the triangle, multiply the hypotenuse side by the sine of the angle given
First, you subtract 15 on each side:
2/3x=17-15
then, you simplify:
2/3x=2
multiply by 3
2x=6
divide by 2
x=3
Answer:
B
Step-by-step explanation:
You would distribute the negative sign in front of -3. -3 would then become 3.
-6 (3)
Then you would place them on a line.
