Answer:
The answer to your question is: 45° and 225°
Step-by-step explanation:
Getting tan⁻¹ 1 = 45°
Then, the angle we are looking for is 45°, let's check the for quadrangles.
First quadrangle = tan 45 = 1
Second quadrangle = 180° - 45° = 135° tan 135 = -1
Third quadrangle = 180 + 45 = 225° tan 225 = 1
Forth quadrangle = 360 - 45 = 315° tan 315° = -1
Step-by-step explanation:
The cost of 800 bricks having dimensions of at a cost of $0.07 per in.³ is <u>$3,797.5</u>
The dimensions of the brick are;
Cost of a cubic inch of brick = $0.07
The volume of 1 brick is therefore;
The volume occupied by 800 bricks is therefore;
Given that the dimensions of the bricks are in inches, the volume of 800 bricks is therefore;
V₈₀₀ = 54,250 in.³
The cost of 800 bricks is therefore;
Total cost = 54,250 in.³ × $0.07 = $3,797.5
The cost of 800 bricks is <u>$3,797.5</u>
