Answer:
142.932
Step-by-step explanation:
given that in triangle ABC, AC =24
Angle A = 30 and Angle B =45
If we draw altitude from C, we get
h = 24sin 30 = 12
Since BC = h (45, 45,90 triangle)
BC=12
By sine formula for triangle

Area of triangle
= 
 
        
             
        
        
        
Hello! here are the basic rules that you need to know to solve these problems:
a diameter is 2 × the radius
the circumference rule is 2×π×radius
I will solve the first question to show how to format.
1: 5/2=2.5
2×2.5×π=5×π=15.7
        
             
        
        
        
Answer:
C)  2 + 3 x - 18
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given expression  2+ 3(x-6)
                  ⇒  2 + 3 x - 18
                ⇒    3 x - 16
 
        
             
        
        
        
Answer:
x = 6
Step-by-step explanation:
13x + 2 = 12x + 8
Because of:
1) Corresponding angles
2) Vertically opposite angles 
13x + 2 = 12x + 8
13x - 12x = 8 - 2
x = 6
