Below is a two-column proof incorrectly proving that the three angles of ? pqr sum to 180: statements reasons ? qry ? ? pqralternate interior angles theorem draw line zy parallel to segment pq construction m? zrp + m? prq + m? qry = m? zry angle addition postulate ? zrp ? ? rpq alternate interior angles theorem m? rpq + m? prq + m? pqr = m? zry substitution m? zry = 180 definition of a straight angle m? rpq + m? prq + m? pqr = 180 substitution which statement will accurately correct the two-column proof?
a.) the measure of angle zry equals 180 by definition of supplementary angles.
b.) angles qry and pqr should be proven congruent after the construction of line zy.
c.) the three angles of ? pqr equal 180 according to the transitive property of equality.
d.) line zy should be drawn parallel to segment qr.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
