Answer:
The smaller angle measures 22 degrees
The larger angle measures 158 degrees
Explanations:
Let the smaller angle be represented by a
Let the larger angle be represented by b
The sum of the two angles equals 180 degrees (Supplementary angles)
a + b = 180...................................(1)
The larger angle is 4 degrees more than seven times the smaller angle:
b = 7a + 4...................................(2)
Substitute equation (2) into equation (1)
a + (7a + 4) = 180
8a + 4 = 180
8a = 180 - 4
8a = 176
a = 176/8
a = 22
Substitute a = 22 into equation (2)
b = 7(22) + 4
b = 154 + 4
b = 158
The smaller angle measures 22 degrees
The larger angle measures 158 degrees
