Angle 1 and 3 are vertical angles, which mean they are identical. Since angle 3 is given as 111 degrees, then angle 1 is also 111 degrees.
All four angles need to equal 360.
Subtract angle 1 and 3 from 360:
360 - 111 - 111 = 138
Angle 2 and 4 would also be identical, so divide the 138 by 2:
138 / 2 = 69
Angle 2 and angle 4 are both 69 degrees.
27
This is because 18* of 23 is 4.14 which rounds to 4, and 23 + 4 = 27.
It's the product of 12 and 5 1/2, so the answer is 66.
Answer:
The interest is $1080 and the amount is $4080.
Step-by-step explanation:
Find an interest by using the formula I=P*i*t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this examplee P = $3000, i = 6% and t = 6 years, so
I=P*i*t
I=3000*0.06*6
I=1080
The interest is 1080, therefore the total amount is 4080.
Hope this helps!
