5.9 = 6
12.087 = 12
4+6+12 = 22
Answer:
20,667.
Step-by-step explanation:
This is an arithmetic series:
3 + 9 + 15 + 21 + 27+ ...........+ 495
First term = 3 and common difference = 6.
Number of terms = ( 495 - 3 )/6 + 1
= 83.
So Sn = n/2(a1 + l) where a1 = first term and l = last term
S83 = 83/2(3 + 495)
= 41.5 * 498
= 20,667.
Answer:
<h2>
m∠M = 123° ; m∠L = m∠N = 90° </h2>
Step-by-step explanation:
A quadrangle LMNP is inscribed in circle which means:
m∠L + m∠N = m∠P + m∠M = 180°
m∠P + m∠M = 180°
57° + m∠M = 180°
m∠M = 123°
m∠L + m∠N = 180° and m∠L + m∠N
m∠L + m∠L = 180°
2×m∠L = 180°
m∠L = 90°
m∠N = m∠L = 90°
