What is a 3 dimensional figure with 3 rectangular faces and 2 triangular faces
me

Answer And with A Explanation:

Hello There. ♡___• •___♡ The correct answer is RO, 270°.

Vertices of Preimage which is in the shape of Triangle RST=R(2,0), S(4,0), and T(1,-3).

Vertices of Image which is obtained after rotation of Triangle R ST=R(O,-2), S(O,-4), and T(-3,-1).

Original Δ RST ,lies on positive X axis and in fourth quadrant.

Image of Δ RST ,lies on negative Y axis, and in third quadrant.

Following are rules of rotation

(x,y)_{90^{\circ}}=(-y,x)(x,y)_{180^{\circ}}=(-y,-x)(x,y)_{270^{\circ}}=(y,-x)

Rotation by 270° has taken place in Preimage ΔRST having vertices R(2,0), S(4,0), and T(1,-3). to obtain Image ΔRST having vertices R(O,-2), S(O,-4), and T(-3,-1).

Hope It Helps!~ ♡
