The length of DE 21.26029163 units
Step-by-step explanation:
log(b³/a)
= logb³ - loga
= 3logb - loga
The possible combination is 1365.
The correct option is (B)
<h3>What is Combination?</h3>
Combinations are also called selections. Combinations correspond to the selection of things from a given set of things. Here we do not intend to arrange things. We intend to select them. We denote the number of unique r-selections or combinations
Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by
nCr = n!/ r!( n- r)!
Given:
Players, n = 15
Selected, r = 11
So,
15 C_11
= 15!/ 11 ! 4 !
= 15*14*13*12 / 4*3*2
= 1365
Hence, the possible combination is 1365.

Answer:
A triangle is equilateral if all three angles are same. but here two angles are 64° but third angle is 52°. so, Yin is incorrect.
Step-by-step explanation:
x = 19,
Putting value of x to find m∠ABC and m∠ACB
m∠ABC = (4x – 12)°
m∠ABC = (4(19) – 12)°
m∠ABC = (76 – 12)°
m∠ABC = 64°
m∠ACB = (2(19) + 26)°
m∠ACB = (38 + 26)°
m∠ACB = 64°
now we know sum of angles of triangle is 180°. We can find the measure of third angle.
180 = 64+64 +x
x= 180 - 64 - 64
x = 52°
A triangle is equilateral if all three angles are same. but here two angles are 64° but third angle is 52°. so, Yin is incorrect.
