Answer:
Therefore the measure of the missing angle x, is 90°.
Step-by-step explanation:
Let name the vertices of a Quadrilateral as ABCD such that
∠A = 107°
∠B = 72°
∠C = 91°
∠D = x
To Find:
x = ?
Solution:
In a quadrilateral,
Sum of the measures of all the angles is add up to 360°
Substituting the values we get
Therefore the measure of the missing angle x, is 90°.
It cannot be reduced any more 168:439
Answer:
3 minutes and 30 seconds
Step-by-step explanation:
7-5 = 2
3/2 = 1.5 gallons that empty per each minute
1.5 times 3 (minutes) = 4.5 gallons emptied
Remaining gallons to empty = 0.5
0.5 gallons to empty will take 30 seconds
