Hey there!
In this picture, we have many pairs of adjacent angles:
1 and 2
2 and 4
4 and 3
3 and 1
This is because these pairs are being connected by a vertex and a side.
Hope it helps and have a great day!!!
Answer:
Option D
Step-by-step explanation:
In the first three options we can evaluate the values of x with the help of Sine Rule for all the triangles
The Rule says

Where a , b and c are the sides opposite to the angles A, B and C of any ΔABC.
Hence , in order to determine unknown values of sides or angles , we need any 3 values from all 3 sides and 3 angles in a triangle. First Three options give us three values but the last option gives only 2.
Example
in first option we can apply Sine Rule as





Answer:
5
(3a²b³c)³(2a⁴b²c²)³
= (3a⁶b⁹c³)(8a¹²b⁶c⁶)
= 24a¹⁸b¹⁵c⁹
14
⁴√(81a¹⁶b¹²c⁹)
= (⁴√81)(⁴√a¹⁶)(⁴√b¹²)(⁴√c⁹)


Answer:
x = 7
Step-by-step explanation:
-6+7x = -2x+57
+6+2x +2x+6
9×/9 = 63/9
× = 7
