Parallelogram RSTU is shown. Ilan needs to prove that segment RS ≅ segment TU and segment RU ≅ segment TS. His proof is shown in the table below. Step Statement 1 RSTU is a parallelogram 2 Side RS || Side TU and Side RU || Side TS 3 ∠RSU≅∠TUS and ∠RUS≅∠TSU 4 Side SU ≅ Side US 5 ΔRSU≅ΔTUS 6 Side RS ≅ Side TU and Side RU ≅ Side TS Select all reasons that support one or more statements in the proof

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information

2y+y=5

add 2y and y

multiply each one by 3.14
