If you mean 40% of the circle with the rotation at the center of the circle, then you do this:
Measure of circle: 360°
Amount of circle's measure: 40%
360 * 40% = 144°
Thus, to take up 40% of the circle you need to have an angle measure of 144°.
Answer:
∠2 = 152
Step-by-step explanation:
A straight angle should always equal 180, and that is really the key to how we answer this problem. That means that ∠1 and ∠2 are supplementary, and add up to 180°.
That means that 180-28, will give us our other angle.
Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.
The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.
Now solve your two equations simultaneously for x and y.
Answer:
y = 7
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, then
AC = BD , that is
AE + EC = BD [ AE = EC = 6y ]
6y + 6y = 84
12y = 84 ( divide both sides by 12 )
y = 7
Answer:
112 ft³
Step-by-step explanation:
→ Length (l) = 7 ft
→ Breadth (b) = 4 ft
→ Height (h) = 4 ft
Formula we use,
→ l × b × h
The volume of cuboid will be,
→ l × b × h
→ 7 × 4 × 4
→ [ 112 ft³ ]
Hence, the volume is 112 ft³.
