Step-by-step explanation:
A parallelogram is a quadrilateral with four sides.
Given parallelogram ABCD, to prove that opposite sides of the parallelogram are congruent.
Join D to B, the diagonal of the parallelogram which is also a traversal.
So that;
<ABD = <BDC (alternate angle property)
<BAC = <ACD (alternate angle property)
Also, diagonals;
/AC/ = /BD/ (reflexive property)
Then;
ΔABD = ΔCBD (Angle-Side-Angle, ASA, property)
Thus;
/AB/ ≅ /CD/ (corresponding sides of congruent triangles are congruent)
/BC/ ≅ /AD/ (corresponding sides of congruent triangles are congruent)
Therefore, the opposite sides of the parallelogram ABCD are congruent.
A) multiply his hourly rate by 1.5
12.50 x 1.5 = $18.75
B) double time is 2 times. Multiply his hourly rate by 2:
12.50 x 2 = $25
I'd start by recognizing that the smaller triangle, at the top, is similar to the larger (whole) triangle.
Then:
a b
------- = ---------
15+a 20+b
Then 20a + ab = 15b + ab. Subtract ab from both sides. We then get 20a = 15b. Note also that
40 b
----- = ----------
60 b+20
so that 40b + 800 = 60b, or 800 = 20b, or b = 40.
If b = 40, then we can find a from the relationship 20a = 15b found earlier. With b=40, 20a = 15(40) = 600, so a = 30
a = 30
b= 40
