Option a:
sin A for the triangle is 
.
Solution:
The given triangle is a right triangle.
The adjacent side to angle A is AC.
The opposite side to angle A is BC.
Hypotenuse is AB.
AC = 8, BC = 6 and AB = 10.
Using trigonometric ratio formulas,
Divide both numerator and denominator by 2, we get
Hence sin A for the triangle is .
Option a is the correct answer.
Answer:
5.8
Step-by-step explanation:
the distance formula is
d =sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt ( (-5 - -2) ^2 + (-1 - -6)^2 )
= sqrt( (-5 +2) ^2 + (-1 +6)^2 )
= sqrt( (-3) ^2 + (5)^2 )
= sqrt( 9+25)
= sqrt(34)
=5.830951895
Rounding to the nearest tenth
5.8
Step-by-step explanation:
(-2a² + s)(5a² - 6s)
= (-2a²)(5a²) + (-2a²)(-6s) + (s)(5a²) + (s)(-6s)
= -10a⁴ + 12a²s + 5a²s - 6s²
= -10a⁴ + 17a²s - 6s². (1st option)
