Answer:
-  ∠R = 56° 
-  ∠Q = 90°
-  ∠S = 34°
Step-by-step explanation:
The given triangle is a right angled triangle. 
So, the angles in the triangle are : 
- 90° 
- (2x + 38)° 
- (5x - 11)°
Solving according to <u>angle sum property</u>, 
Sum of all angles in a triangle is 180° 
 90° + (2x + 38)° + (5x - 11)° = 180°
 90° + (2x + 38)° + (5x - 11)° = 180°
 117° + 7x = 180°
 117° + 7x = 180°
 7x = 180° - 117°
 7x = 180° - 117° 
 7x = 63°
 7x = 63°
 x = 9
 x = 9 
Angles = 
 2(9) + 38
 2(9) + 38
 56°
 56° 
 5(9) - 11
 5(9) - 11
 34°
 34° 
-  ∠R = 56°
-  ∠Q = 90°
-  ∠S = 34°
The angles are 56°, 90° and 34°.
 
        
             
        
        
        
I got X=11
Minus 7x on both sides
The equation the becomes :
-2x +179=157
Subtract 179 from both sides
Equation now is: 
-2x= -22
Divide -2 on both sides
X= 11
        
             
        
        
        
Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x² 
     For x = a,
     f(a) = 8a²
     Now substitute these values in the expression,
      =
 = 
                   = 
                   = 
                   = 8(x + a)
b).  =
 = 
                       = 
                       = 
                       = (8h + 16x)
                       = 8(h + 2x)
 
        
             
        
        
        
Answer:
42 cm cubed
Step-by-step explanation:
6x4x4 to find volume of 96 when it is filled.
3x3x6 = 54 to find out what is cut out.
96-54 = 42 cm cubed.
