Subtract 31 from 90 and you will get 61 degrees all complement angles add up to be 90°
Answer:
Angle 1: 52 degrees
Angle 2: 128 degrees
Step-by-step explanation:
Angle 1 = x
Angle 2 = 2x + 24
Supplementary angles are two angles that add up to 180 degrees.
x + 2x + 24 = 180
3x + 24 = 180
3x = 180 -24
3x = 156
x = 52
Check:
Angle 1: x = 52
Angle 2: 2x + 24
2(52) + 24
104 + 24 = 128
128 + 52 = 180
_____
1.7 | 45.78
ok....we want to make the 1.7 into a whole number....we do this by moving the decimal 1 space to the right.....and since we move the decimal one space on the divisor, we need to move the decimal 1 space on the dividend.
so ur problem would now be :
______
17 | 457.8
Answer:
6774.075
Step-by-step explanation:
1984: 8855
1983: 8855*10/100=885.5
8855-885.5
7969.5
1982
7969.5*15/100=1195.425
7969.5-1195.425
6774.075
33 rounds to 30 and 89 rounds to 80. 80 x 30= 2400
