Answer:
3. m∠A < 80°
Step-by-step explanation:
The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.
If we assume that angle measures cannot be zero, then we must have ...
m∠A +m∠N = 80°
m∠A = 80° -m∠N
Since m∠N > 0, the measure of angle A must be less than 80°.
This conclusion matches choice 3.
Given number is 4,8100,000,000,000.
In this number of zero is 11. So we can write it as
But for scientific notation we will enter decimal after two place in reverse direction.For this we will also multiply number by 10^2.
So number will be
So fourth option is correct.
7+18/(6-3)
7+18/3
25/3=8.333
