Answer:
<A = 75degrees
Step-by-step explanation:
From the triangle given;
arcDA + arc AD + arcBD = 360 degrees
131 + 79 + arcBD = 360
210 + arcBD = 360
arcBD = 360 -210
arcBD = 150 degrees
Since the angle at the vertex <A is half that at the arc BD, hence;
<A = 1/2 arcBD
<A = 1/2 * 150
<A = 75degrees
Hence the measure of angle A s 75degrees
Answer:
B) -350
Step-by-step explanation:
We are given the sequence:
-56, -59, -62, -65...
And we want to determine its 99th term.
First, note that we have an arithmetic sequence. This is because each subsequent term differs from the previous term by a common difference.
In this case, each subsequent term is 3 less than the previous term, so our common difference <em>d</em> is -3.
To find the 99th term, we can write an explicit formula. The explicit formula for an arithmetic sequence is:
Where <em>x_n</em> represents the <em>n</em>th term, <em>a</em> is the initial term, and <em>d </em>is the common difference.
Since the first term is -56, <em>a </em>= -56.
By substitution, we acquire:
The 99th term is when <em>n</em> = 99. Thus:
Evaluate:
Our answer is B.
10 less then 'n' is a way of saying take ten away from 'n'.
it represents subtraction
basically n - 10
Answer:
0 , 4 , 8
Step-by-step explanation:
Multiples of 4 = 12,16,18,20, 24, 28.............100, 104, 108, 112, 116,120, 124, 128
Numbers that have even no. in tens = 20, 24 , 28 ... 100, 104, 108, 120 , 124, 128
As evident, all these numbers (including those > 100) have 0, 4, 8 as one's place numbers.
