.
Step-by-step explanation:
The answer is A. u do the othe angle and add it to the fisrt one
Answer:
x = 68°
Step-by-step explanation:
∠ DCB = ∠ EDC = 27° ( alternate angles )
Thus ∠ ECB = 23° + 27° = 50°
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (62 + 50)° = 180° - 112° = 68°
Answer: D) (1.2,-4.7)
Step-by-step explanation:
plug in the end corrdinates like it says in the equation that the problem gives you.
Step-by-step explanation:
We can use the formula to find the number of moles. As ,
n = No. of particles/ N_A
n = 3.01× 10¹⁸/6.022 × 10²³
n = 1/2 / 10⁵
<h3>Hence the number of particles is 1/2 / 10⁵ </h3>
