Question

Find the value of the angles x, y and z​

Answer 1

Answer:

$x = 115 \: \: \: \: \: \: \: \: \: y = 140 \: \: \: \: \: \: \: \: \: \: z = 40.$

Step-by-step explanation:

$40 + x + 25 = 180 \\ \\ x + 65 = 180 \\ \\ x = 180 - 65 \\ \\ x = 115 \: degrees \\ \\ x + 25 + z = 180 \\ \\ 115 + 25 + z = 180 \\ \\ z = 180 - 140 \\ \\ z = 40 \: degrees \\ \\ y + 40 = 180 \\ \\ y = 180 - 40 \\ \\ y = 140.$
