Answer: second option.
Step-by-step explanation:
By definition, the measure of any interior angle of an equilateral triangle is 60 degrees.
Based in this, we know that the measusre of the angle ∠SRT is:
The, we can find the value of "y":
To find the value of "x", we must use this identity:
In this case:
Substituting values and solving for "x", we get:
This is the concept of combination. The number of letter-sequence that are possible to be formed from the letters q,u,a,k,e,s will be evaluated as follows:
Total number of letters is 6
Maximum number of letters in a word is 4
thus the number of four letter sequence that can be formed will be:
6C4
=15
The reason why we are using combination is because no letter can be used more than once in each sequence.
F=1.8C+32, and we are told that C=10 so
F=1.8(10)+32
F=18+32
F=50°
15/3 = 5
5 * 2 = 10
There are 15 boys and 10 girls in the classroom.
