Question

Please help me friends

Answer 1

$1) \: 127 + (5x + 3) + 88 + (10x + 7) = 360$

$225 + 15x = 360$

$15x = 360 - 225$

$15x = 135$

$x = \frac{135}{15} = 9$

$5x + 3 = 15 \times 9 + 3 = 138$

$10x + 7 = 10 \times 7 + 7 = 77$

$2)w = 60$

$corresponding \: angles$

$z = 180 - 60 = 120$

$x = 180 - 60 = 120$

$y = 180 - 80 = 100$

$(linear \: pair)$

$x = 50 \: \: (alternate \: int. \: angles)$
