Question

Find the values of each of the angles marked in Fig. 13.15. 70⁰ 13.15 28​

Answer 1

y = 120 degrees
x = 60 degrees

y plus the angle next to it will make 180 degrees since they form a straight line. This means we need to find 180-angle to find y. Let’s call this angle z.

z is the third angle in a triangle with other angles 50 and 70. This makes it equal to 180-50-70 = 60 degrees.

y = 180-z = 180 - 60 = 120

x = 180 - y - 28 = 180 - 120 - 28 = 32
