If ST bisects RSV, m RST =5x-3 and m VST=2x+15 then choose an equation that could be used to solve for x

Doss [256]

Answer:

x = 6

Step-by-step explanation:

$\because ST \: bisects\: \angle RSV\\\therefore m\angle RST = m\angle VST\\(by\: \angle \: bisector \: property) \\\therefore 5x - 3 = 2x + 15\\\therefore 5x - 2x = 15 +3\\\purple{\bold {\therefore 3x = 18}} \\\therefore x =\frac{18}{3}\\\huge \orange {\boxed {\therefore x = 6}}$

Find the volume of a triangular prism with the following dimensions. Round to the nearest whole number.

mestny [16]

The volume of any prism is just the area of the base times the height of the prism.

The base of the prism is a triangle, and you should know how to find the area of a triangle already. The base is 9, the height is 4, $\frac{bh}2=\frac{9*4}2=\frac{36}2=\boxed{18\ ft^2}$ .

Multiply that by the height of 9.5 and we get $18\ ft^2*9.5\ ft=\boxed{\boxed{171\ ft^3}}$
