The length of the base angle is triangle
DanielleElmas [232]3 years ago
4 0

Answer:

70 degrees

Step-by-step explanation:

since an isosceles triangle is symmetrical, i cut the triangle in half (vertically) so that it became a right triangle. so the angle sides are now 20 degrees at the top, 90 degrees (right angle, where it was cut), and x degrees. 20 + 90 + x = 180 degrees (total amount of degrees in a right triangle) x = 70 degrees.

hope this helps!

Let the rational between the three numbers be x, hence the three numbers be 2x, 3x,and 4x.


If their average is 36, what are the numbers

We know the average = sum of the numbers / no. Of numbers.

(2x+3x+4x) /3=36

Elias was given a lock for his school locker. The lock contains numbers between
daser333 [38]

Answer:

34,220

Step-by-step explanation:

Because order doesn't matter, but the numbers can't be repeated, we need to find the number of combinations where 3 individual numbers can be chosen out of 60 possible numbers using the binomial coefficient:

\binom{n}{k}=\frac{n!}{k!(n-k)!}\\ \\\binom{60}{3}=\frac{60!}{3!(60-3)!}\\\\\binom{60}{3}=\frac{60!}{3!(57)!}\\\\\binom{60}{3}=\frac{60*59*58}{3*2*1}\\ \\\binom{60}{3}=34220

Thus, Elias can make 34,220 unique 3-number codes given 60 different numbers.
