Answer:
number 4.     13
because first you do the exponents giving you 8 and then divide which is 2 then you subtract which is 13
 
        
                    
             
        
        
        
Answer:
t = 14
Step-by-step explanation:
 log (7t + 2) = 2
Raise each side to the power of 10
 10 ^log (7t + 2) =10^ 2
7t+2 = 100
Subtract 2 from each side
7t+2-2 = 100-2
7t = 98
Divide each side by 7
7t/7 = 98/7
t = 14

A triangle is a three-edged polygon with three vertices. Only the law of Sine can be applied to solve the triangle.
<h3>What is a triangle?</h3>
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
The sum of all three angles can be written as,
118° + 22° + x = 180°
x = 40°
For the sine rule to be applicable, two angles and a side or an angle and two sides are needed. Therefore, the law of Sine can be applied to solve the triangle.
For the cosine rule to be applicable, two sides and an angle between them is needed to be known, hence, the law of cosine can not be applied.
Hence, Only the law of Sine can be applied to solve the triangle.
