None of the answers are correct it’s -28
Answer:
150° and 210°
Step-by-step explanation:
1) to drow a circle with radius=1 in the system of coordinates like in the attached picture;
2) to mark point (-√3/2)≈-0.866 on X-axis (in the picture it is the point M);
3) to graph line AB through point M, the line AB || Y-axis and the points A and B are on the circle with radius=1;
4) to measure the angles ∠ROA and ∠ROB (the points are marked with red colour);
5) finally, m(∠ROA)=150°; m(∠ROB)=210°.
Answer: 259.2
Step-by-step explanation:
Hi, since the shoe box is a rectangular prism we have to apply the next formula to calculate the surface area if the box:
Surface area (A) = 2wl + 2lh + 2hw
Where:
w = width
l = length
h = height
Replacing with the vales given:
A = 2 (6x 10)+ 2 ( 10x3)+ 2 (3x 6)
A = 2 (60) + 2 (30) + 2(18)
A = 120+ 60+36
A =216 inches
Since she needs 20% more than the total surface area in gift wrap, we have to multiply the total surface area by the 20_% in decimal form, and then add that value to the total surface area.
216 x (20/100) = 43.2
Adding that value to the total surface area:
216 + 43.2 = 259.2 square inches
