<span>Given
numbers 12.6, 3.1 and 5.4
=> 12.6
=> 3.1
=> 5.4
These 3 are all smaller than 20.
Explain why is it greater than 20?
Very simple, simply add those given numbers
=> 12. 6 + 3.1 = 15.7
=> 15.7 + 5.4 = 21.1
=> 21.1 > 20 , 20 is less than 21.1
That’s that reason why the given numbers is greater than 20. When you add the 3
numbers, the sum is greater than 20.</span><span>

Answer:
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Step-by-step explanation:
m ∠A + m ∠B = 90° Complementary angles sum = 90°
7x + 4 + 4x + 9 = 90
11x + 13 = 90
11x = 77
x = 7
angle A = 7(7) + 4 = 49 + 4 = 53°
angle B = 4(7) + 9 = 28 + 9 = 37°
Check = angle A + angle B = 90° checked
