Find the measure of angle A. 66° x +49 x+83

liubo4ka [24]

Step-by-step explanation:

Since , internal sum of angle of triangle is 180°

So,

66 + x +49 + x+83 = 180

or, 198 + 2x = 180

or, 2x = 180 -198

or, 2x = -18

hence, x = - 9

Now angle A = x + 49

= (-9) + 49

= 40

Hence measure of angle A is 40°.

The 16th term of an A.P. is 40 and the sum of the first 5 terms is 5. Find the sum of the first 50 terms.

KiRa [710]

Answer:

The sum of first 50 terms is 3425.

Step-by-step explanation:

Let the first tem of A.P be 'a' and it's common difference be 'd'

Thus the 16th term of the A.P is given by

$T_n=a+(n-1)d\\\\40=a+15d..........(i)$

Now we know that the sum of first 'n' terms of the A.P is given by

$S_n=\frac{n}{2}[2a+(n-1)d]\\\\5=\frac{5}{2}[2a+4d]\\\\1=a+2d..........(ii)$

Solving equation 'i' and 'ii' simultaneously we get

$40=1-2d+15d\\\\13d=39\\\\\therefore d=3$

Thus $a=1-2\times 3=-5$

Thus the sum of first 50 terms euals

$S_{50}=\frac{50}{2}[2\times -5+(50-1)3]\\\\S_{50}=3425.$
