If a series of rigid transformations maps ∠F onto ∠C where ∠F is congruent to ∠C, then which of the following statements is true?

triangles ABC and FDE, in which angles A and D are right angles

a) ΔABC ~ ΔFDE because of the definition of similarity in terms of similarity transformations

b) ΔABC ~ ΔFDE because of the AA similarity postulate

c) segment BC ~ segment EF because of the definition of similarity in terms of similarity transformations

d) segment BC ~ segment EF because corresponding parts of similar triangles are similar

to complete this square you have to rotate about the origin 270 degrees clockwise.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.

i think the answer is b x = 1, y = 35/2
