Answer:
1. R = 8 ohms 2. V = 32 volts
Step-by-step explanation:
<h3>1. We have,</h3>
Voltage, V = 16 V
Current, I = 2 A
We need to find the resistance of the circuit. Using Ohm's law,
V = IR
So,
2. Current, I = 8 A
Resistance, R = 4 ohms
We need to find the voltage of the circuit. Using Ohm's law again,
V = 8 × 4
V = 32 volts
Hence, this is the required solution.
Problem 42 is 4 because 2(3+4)= 14 So 2x3 is 6. (14-6=8) so them 2x4 is 8.
Problem 43 is 6 because 5(6+3)= 45 So 5x3 is 15 (45-15=30) and 5x6=30
In problem 44 7x4=28 and 4x5=20 so you do 28+20 to get 48. (48 divided by 4 is 12) So 12-7 is 5. 5 is the answer
Problem 45: 6x4=24 and 6x3=18. 24+18=42. (42 divided by 6 is 7) so the last one could be anything added together to make 7.
Ex: 6+1 5+2 4+3
Answer:

Step-by-step explanation:
Answer:
The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with
N sides. It is equal to 360
o
N
.
Step-by-step explanation:
Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.
However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to 360
o
.
It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of
360
o
. So, if all exterior angles are equal, like in a regular polygon, each one equals to 360
o
N
.
It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is (

Dividing the above by N
