Answer:
m ∠ABD = 140°
m ∠DBC = 40°
Step-by-step explanation:
∠ (15x - 4) + ∠(5x - 8) = 180°
15x - 4 + 5x - 8 = 180
20x -1 2 = 180
20x = 180 + 12
x = 9.6
m ∠ABD = 15x - 4 = 140°
m ∠DBC = 5x - 8 = 40°
Answer:
4. A rectangle is a square
Step-by-step explanation:
A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.
Answer:
39.43 for each dog
Step-by-step explanation:
<u>d = 2c (given) </u>
164 c + 23 d = 4140 sub in the above equation for d
164 c + 23<u> (2c)</u> = 4140
210c = 4140
c =19.71
d = 2c = 39.43
