Step-by-step explanation:
Complementary angles sum to 90°, thus
∠A ∠B = 90 ← substitute values
5x - 27 + 4x - 27 = 90, that is
9x - 54 = 90 ( add 54 to both sides )
9x = 144 ( divide both sides by 9 )
x = 16
Hence
∠A = 5x - 27 = (5 × 16) - 27 = 80 - 27 = 53°
∠B = 4x - 27 = (4 × 16) - 27 = 64 - 27 = 37°

Answer:
Step-by-step explanation:
In this problem we assume that
Segment PL, Segment AE and Segment RT are parallels
so
using proportion
we have
Remember that
substitute the values and solve for LE
Multiply in cross
to find out the amount we have to divide the amount of gallons by time
12/5= 2.4
one minute would use 2.4 gallons
