A triangle has the area of 1/2(4x^2+29x+30)ft^2. If the base of the triangle is (x+6) ft, find the height of the triangle.

Paul [167]

Answer:

4x+5 ft

Step-by-step explanation:

1/2(4x²+29x+30) = 1/2 (x+6) * Height

Height = (4x²+29x+30) / (x+6) = (x+6) (4x+5) / (x+6) = 4x+5

Answer:

Step-by-step explanation:

sin2x = 2sinx*cosx

= $2\sqrt{sin^{2}x }$ * cosx

= $2\sqrt{(1-cos^{2}x }$ * cosx

= 2 $\sqrt{1-\frac{3}{5} ^{2} } *\frac{3}{5}$

= $\frac{8}{5} * \frac{3}{5}$

= 24/25
