The little lines inside the two angles mean they are the same.
The 3 inside angles of a triangle equal 180 degrees.
One angle is 146 , so the other two need to equal 180-146 = 34 total.
34/ 2 = 17
Both angle 1 and angle 2 are 17 degrees each.
Answer:
x = 74°
Step-by-step explanation:
The diagram shown in this question, is a Quadrilateral inscribed in a circle
It is important to note that
The sum of opposite angles in a Quadrilateral = 180°
93° + z = 180°
z = 180° - 93°
z = 87°
In a cyclic quadrilateral,
Intercepted angle = 1/2(Intercepted arc)
Intercepted angle = 93°
Intercepted arc = x + 112°
Hence,
93° = 1/2(x + 112)°
93° × 2 = x + 112°
186° = x + 112°
x = 186° - 112°
x = 74°
The quantity that is present after 2000 years will be A. 7.851 grams.
<h3>How to calculate the quantity?</h3>
From the information given, initially at t = 0, the quantity is 10 grams.
After 2000 years, the appropriate quantity will be:
Q(2000) = 10 (1/2) × (2000/5730)
Q(2000) = 7.851 grams.
In conclusion, the correct option is A.
