(3x+1)(5x-2)
Just replace x as 3 and then solve as usual :)
Answer:
options are provided below...i hope this helps! :)
Step-by-step explanation:
well if the angles are vertical then ADC would be the same as ABC with 40 degrees
if the angles are corresponding, then they both are 40 degrees
if they are complementary angles, then they add up to 90 degrees
so the angle ADC would be 50 degrees
if they are supplementary angles, then they add up to 180 degrees. so ADC would be 140 degrees

Answer:
m∠1 = 39.5°
m∠2 = 39.5°
m∠3 = 50.5°
m∠4 = 50.5°
Step-by-step explanation:
m∠1 = 39.5° (Given)
m∠2 = m∠1 = 39.5° (∠1 ≅ ∠2)
m∠3 = 90° - 39.5° = 50.5° (∠1 and ∠3 are complementary)
m∠4 = m∠3 = 50.5° (∠1 ≅ ∠2, ∠2 and ∠4 are complementary)
Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is 
. The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is 
. Hence, the correct option is (b).
