Answer:
But there is no question. And the formula for the area of a triangle is 1/2bh not 1/2h.
Thank you.
 
        
             
        
        
        
Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides =  :
 :  = 1 : 3
 = 1 : 3
Thus side of B is 3 times side of A 
x = 3 × 2 = 6 cm
 
        
             
        
        
        
Answer:
9) x = 89°
10) x = 118°
11) x = 145°
12) x = 40°
Step-by-step explanation:
9) 180-91 = 89
10) x = 118° because it is alternate interior to 118
11) x-30 = 115,     x = 145
12) 4x-15 = 145,    4x = 160,   x = 40

Answer:
B)
Step-by-step explanation:
The slope is 2/4=1/2
The y-intercept is 3
Given the shaded area, y is going to be less than or equal to.
So B is correct
