Answer:
60°
Step-by-step explanation:
Complementary angles sum to 90° , then
x + x + 30 = 90
2x + 30 = 90 ( subtract 30 from both sides )
2x = 60 ( divide both sides by 2 )
x = 30
Then
larger angle = x + 30 = 30 + 30 = 60°
Answer:
3x0.9, 30x9, 3/1000 times 9/10000
Step-by-step explanation:
Multiply each factor by multiples of ten.
4/5 is equal to 0.8 when you divide 4 by 5. 2/3 is 0.66 when you divide 2 by 3. So 4/5 is bigger than 2/3.
