In δpqr, the obtuse angle is 105°, and the shorter sides measure 4 and 7 units. triangle p q r is shown. rounded to the nearest tenth, what is the area of δpqr? area = square units

55? i think maybe

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.

if e is the midpoint of bd, then bd is 14.

step-by-step explanation:

8.3 and the 3 is repeating

hope this .
