9. Look at triangle RST below.<br><br> Which side of the triangle is the longest?
Lera25 [3.4K]

Answer:

ST is longest

Step-by-step explanation:

  • <em>Theorem: </em>
  • <em>If one side of a triangle is longer than another side, then the angle opposite the longer side will be larger than the angle opposite the shorter side</em>

The values of the angles are:

  • ∠S= 50°,
  • ∠T= 60°,
  • ∠R= 180°- (50°+60°)= 180° - 110° = 70°

Since ∠R is the largest angle, the side ST is longest

castortr0y [4]

Answer:

20 sin³O. cos²O - 5sin⁵O

Step-by-step explanation:

y = sin⁵O

Using the Chain Rule

dy/dO = 5 sin⁴O cosO

Using the Product / Chain rules:

d²y/dO² = 20 sin³O.cosO . cos O+ 5 sin⁴O * - sin O

= 20 sin³O. cos²O - 5sin⁵O
