Here we can see that ∠b is vertically opposite to 68° angle and we know that vertically opposite angles are equal.
So , the measure of ∠ b will also be equal to 68° .
More to know :
- Alternate Interior angles are equal.
- Corresponding angles are equal.
- Sum of co - interior angles is 180° .
- Alternate exterior angles are equal.
- Measure of angle of straight line is 180°.
- Vertically opposite angles are equal.

(1) The correct answer is: Pressure = P = 70 N/m²
Explanation:
Pressure is force per unit area. Mathematically, we can write Pressure as follows:
</span>

<span> --- (1)
Where P = Pressure = ?
F = Force = 140N
A = Area = 2.0m²
Plug in the values in (1):
P = 140/2.0
P = 70 N/m²
(2) The air particles in the inflated balloon are in chaotic motion. They are moving randomly and colliding with each other and with the inner wall of the balloon, exerting pressure on the wall of the balloon. Furthermore, they are far apart from each other, which is why when you squeeze the balloon, its shape changes accordingly as long as you are putting pressure on it while squeezing. </span>

Answer:
Step-by-step explanation:
Now sum of infinite series is

r
and if first three term are removed, fourth term becomes the first term i.e. first term becomes
a
r
3
and
sum of infinite series becomes
