Answer:

x=81

y=99

z= 129

Step-by-step explanation:

the 3 angles of a triangle add to 180 degrees

51 + 48 + x = 180

99 + x = 180

subtract 99 from each side

99 + x -99 = 180 -99

x = 81


x+y = 180  they make a straight line

81+ y = 180

subtract 81 from each side

y = 180-81

y = 99


z+ 51 = 180  they make a straight line

subtract 51 from each side

z+51-51 = 180 -51

z = 129
1.
x=81
51+48+x=180
99+x=180
x=81°

2.
180°-81=99°

3.
180-51= 129°
