Answer:
13. 
Let us say 
first angle be = 4x -10
second angle = x
now add them to 90 as complementary angles add up to 90
4x - 10 + x = 90
5x - 10 = 90
5x = 90+10
5x = 100
x = 100/5
x = 20
the first angle = 4x -10
                        = 4(20) -10
                        = 80 -10
                        = 70
the second angle = x
                              = 20
the angles are 70 and 20
 
        
             
        
        
        
Answer:
A) length = 9cm, width = 4 cm
Step-by-step explanation:
The key word "times" refers to multiplication, so if you're trying to find dimensions at 1/4 times its original size, you need to multiply the original dimensions by 1/4.
l = 36
new l = 36 (1/4)
           = 36/4
           = 9 cm
w = 16
new w = 16 (1/4)
             = 16/4
             = 4 cm
