Answer:
x = 60 degree
Step-by-step explanation:
90 + 90 + 2x - 10 + 2x + 2x + 10 = 540 degree (sum of 5 interior angles)
180 + 6x = 540
6x = 540 - 180
x = 360/6
x = 60 degree
18×12.80=230.40 (class total)
11×12.80=140.80 (1st day)
230.40-140.80=89.60 (amount paid on 2nd day)
Other way
18-11=7
7×12.80=89.6
Answer:
130/l in where l is the length of the rectangle
Step-by-step explanation:
The formula for area of a rectangle is length by width where the width is the height of the rectangle
Given that area=130 in²
Lets assume the length of this rectangle is =l inches
Then ;
A=l*w
130 =l*w
130/l = w
130/l in = height
Answer:
b
Step-by-step explanation:
complex solutions occur in conjugate pairs, hence
+ 5i , then - 5i is also a solution
