Answer:
From given relation the value of β is 37.5°
Step-by-step explanation:
Given as :
α and β are two acute angles of right triangle
Acute angle have measure less than 90°
Now given as :
= 
Or, 
=
SO, 
= 
Or, 90° = + 
or, 90° = 
+ 4x
Or, 90° = 
So, x = 
= 15°
∴ = 
So, = sin
∴ The value of Ф_1 = = 37.5°
Similarly = 
So ,The value of Ф_2 = 
= 52.5°
∵ β 
α
So, As 37.5°52.5°
∴ β = 37.5°
Hence From given relation the value of β is 37.5° Answer
Step-by-step explanation:
3x - 2y = 12
Substituting y = 9, we find:
Similarly, solving for point B (4, __) =B (4, 0)

Step-by-step explanation:
Lilly should re-estimate the original numbers to be smaller.
for example if she rounded to 10 and 20, she should go back and check and re-round to maybe 8 and 10
Both sets of numbers have the same factors:
12 × 12:
= (2× 2× 3) × (2 × 2 × 3)
= 2^4 × 3^2
6 × 24
= (2 × 3) × (2 ×2 × 2 × 3)
= 2^4 × 3^2
