Answer:

19

Step-by-step explanation:

PA and TR are parallel which makes angle P and T supplementary(they add up to 180)

This means we can add 5x+9 to 4x to equal 180

5x+9+4x=180

9x+9=180

9x=171

x=19

ILL GIVE BRAINLIEST! PLEASE HELP I DONT UNDERSTAND!
blsea [12.9K]

Answer:

S₁₅ = 645

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Using the nth term formula a_{n} = 5n + 3 , then

a₁ = 5(1) + 3 = 5 + 3 = 8

a₂ = 5(2) + 3 = 10 + 3 = 13 , then

d = a₂ - a₁ = 13 - 8 = 5

Thus

S₁₅ = \frac{15}{2} [ (2 × 8) + (14 × 5) ]

     = 7.5( 16 + 70)

     = 7.5 × 86

     = 645
