Answer:
A = 40°
B = 50°
Step-by-step explanation:
If cos A = sin B, then A + B = 90
So, 2x/3 + 20 + 2x - 10 = 90
2x + 60 + 6x - 30 = 270
8x + 30 = 270
8x = 240
x = 30
2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40
2x - 10 = 2(30) - 10 = 60 - 10 = 50 or 90 - 40 = 50
First, you need to distribute the right side of the equation : 8n - 2
Now the equation is : 20 - 7n = 8n - 2
Add 2 to both sides : 22 - 7n = 8n
Add 7n to both sides : 22 = 15n
Divide both sides by 15 : ( I had to round this one) 1.5 = n

Answer:
I think 4 x 3.2/5 is higher or greater because the values which it is multiplying a very high and the value at which 3 ×4.2/ 5 is very low compared to the first value

The formula is as follows
V = L*W* H
V = 12.1 cm * 5.3 cm * 4.2 cm
V =269.346 cm^3
rounded to the nearest tenth
V = 269.3 cm^3
