Answer:
![\frac{\text{AB}}{\text{DB}}=\frac{\text{CB}}{\text{EB}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BAB%7D%7D%7B%5Ctext%7BDB%7D%7D%3D%5Cfrac%7B%5Ctext%7BCB%7D%7D%7B%5Ctext%7BEB%7D%7D)
Step-by-step explanation:
Since AC || DE, and ABC forms a triangle, we can deduce that ABC is a smaller triangle inside triangle DBE.
In the second step, we see that ∠CAB in the smaller triangle is congruent to ∠EDB in the larger one, due to the corresponding angles theorem. We also see that ∠ACB in the smaller triangle is congruent to ∠DEB in the larger one, again by the corresponding angles theorem.
This leads to the third step; since we have two of the angles in one triangle congruent to the corresponding angles in the other triangle, this means the third angle will be congruent (since all triangles equal 180°, and the first two angles are equal, the third must be equal as well). Two triangles in which all three angles of one triangle are congruent to the three angles of the other are similar triangles.
Since the triangles are similar, corresponding sides have the same ratio. This means that the ratio of AB to the larger side DB is the same as the ratio of CB to the larger side EB; this gives us
AB/DB = CB/EB.
Answer:
![x - 7.1 = 8.8](https://tex.z-dn.net/?f=x%20-%207.1%20%3D%208.8)
Step-by-step explanation:
where x represents his original number. to solve and find his original number, add 7.1 to both sides.
Answer:
b = cd / a
Step-by-step explanation:
cd / b = a
cd = a * b
b = cd / a
Answer: $25639.04
plz mark me as brainliest took long time to type
Step-by-step explanation:
i am doing the method in which u find the simple interest of first year then second year
SI FOR 1ST YEAR= P X R X T / 100
SI = 23600 X 2 X 4 / 100
SI = 1888
SI FOR SECOND YEAR =
P = 23600 + 1888= 25488
SI = 25488 X 2 X 4 / 100
SI= 2039.04
COMPOUND INTEREST (CI) = PRINCIPLE + SI OF 2ND YEAR
CI =$25639.04
or u can solve be the method
CI = amount - principle
Amount= principle x (change in ratio) raised to time
Answer:
c .
