15000 * (1+ 0.03)^4
15000 *1.1255 = 16882.63 total after 4 years
16882.63 - 15000 = 1882.63 total interest
Answer is D
Answer:
Step-by-step explanation:
BD=BL(given)
so ∠BLD=∠BDL=3x
90+∠GBD+30=180
∠GBD=180-120=60°
Also ∠GBD=∠BLD (given)
so ∠BDL=60°
3x=60
x=20°
Answer:
h = 3.62
Step-by-step explanation:
First, as both triangles have the same angles we can use the relationship of areas and sides corresponding to similar triangles as follows:
Now we know that the new triangle has sides of 4.18. Then, as these triangles are equilateral we can use the Pythagorean Theorem to find the height:
Finally the height of this new triangle is 3.62 cm
A = 1/2aP
P = number of sides x length of each side
P = 8 x 5.8
P = 46.4
A= 1/2 x 7 x 46.4
A = 162.4
