Answer:
45 degrees
Step-by-step explanation:
A full circle is comprised of 360 degrees, so 360-315=45 degrees.
Suppose the English could drill the Channel in 6.2 years, then they drill with speed
km per year, where L is the length of the English Channel. If the French could drill in 5.8 years, then their speed of drillling is
km per year.
Together their speed will be
.
If they drill together, they will spend
years.
Answer: it would have taken nearly 3 years.

Answer:
$12,415.48
Step-by-step explanation:
A = P (1 + r/n)^(nt)
where A is the final amount,
P is the initial amount,
r is the annual interest rate as a decimal,
n is the number of compoundings per year,
and t is the number of years.
A = 8000 (1 + 0.152/2)^(2×3)
A = 8000 (1.076)^6
A = 12415.48
Answer:
Option A 90,68


Step-by-step explanation:
see the attached figure to better understand the problem
The figure shows a kite
we know that
A kite properties include
1) two pairs of consecutive, congruent sides
2) congruent non-vertex angles
3) perpendicular diagonals
Find the measure of angle 1
we have that
----> by the diagonals are perpendicular
Find the measure of angle 2
we know that
triangle AEB is congruent with triangle CEB
so

In the right triangle EAB
----> by complementary angles in a right triangle
so

therefore
