Find the 74th term of the arithmetic sequence -8, 0, 8

love history [14]

Answer:576

Step-by-step explanation:

-8,0,8,...

Common difference=d=8-0

d=8

First term=a=-8

Using the formula

Tn=a + d x (n-1)

T74 = 74th term

T74=-8 + 8 x (74-1)

T74=-8 + 8 x 73

T74=-8 + 584

T74=576

The 74th term=576

A quadrilateral has three angles that measure 90 100 and 120 which is the measurement of the fourth angle

Lesechka [4]

Answer:

The final angle is 50

Step-by-step explanation:

All quadrilaterals have interior angles that add up to 360. So we can subtract these numbers from 360 to get the final angle.

360 - 90 - 100 - 120 = 50
