Answer:
Larger angle: 80 degrees
Smaller angle: 10 degrees
Step-by-step explanation:
complementary angles = two angles that add up to 90 degrees
x = larger angle
x + x - 70 = 90 Add like terms
2x - 70 = 90 Add 70 on both sides
2x = 160 Isolate the variable by dividing 2 on both sides
x = 80
x = larger angle , 80 degrees
x - 70 = smaller angle , 10 degree

Answer:
x = 15
Step-by-step explanation:
3x - y = 30
Let y = 15
3x - 15 = 30
Add 15 to each side
3x-15+15 = 30+15
3x= 45
Divide each side by 3
3x/3=45/3
x = 15
