8 tens plus 80 tenths and 8 hundredths
It would be a closed circle or "dot" since it is a less than or equal to sign.
Answer:
Yes because 10 times 8 is 80.
Step-by-step explanation:
If i've got the distance of the golden gate bridge right ,then it should be 20.88,you can round that up to either 20 or 21
Answer:
The measure of all the angles are;
45°, 135°, 45°, and 135°
Step-by-step explanation:
The given parameters are;
The ratio of two adjacent angles of the parallelogram = 1:3
Let x represent one of the adjacent angles, and let y represent the other adjacent angle
Given that two adjacent angles of a parallelogram are supplementary, we have;
x + y = 180°
x:y = 1:3
Therefore, y = 3 × x = 3·x, which gives;
x + 3·x = 180°
4·x = 180°
x = 180°/4 = 45°
y = 3 × x = 3 × 45° = 135°
Given that opposite interior angles of a parallelogram are equal, we have, the measure of all the angles are;
45°, 135°, 45°, and 135°.
