Answer:
-6 ≥ r
Step-by-step explanation:
–5 ≥ 5 (r+5)
Divide each side by 5
–5/5 ≥ 5/5 (r+5)
–1 ≥  (r+5)
Subtract 5 from each side
-1-5 ≥ r+5-5
-6 ≥ r
 
        
             
        
        
        
Answer:
B = 61.0
Step-by-step explanation:
Since this is a right angle, we can use trig functions
sin theta = opp side/ hypotenuse
sin B = 7/8
Take the inverse of each side
sin ^-1 ( sin B) = sin ^ -1 (7/8)
B =61.04497563
To the nearest tenth
B = 61.0
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Since this is a right angled triangle:
tan(∅) = opposite side/adjacent side
In this triangle:
tan(25°) = x/19
x = 8. 86 ≅ 8.9
