Answer:

The angle from the centre of Ann's slice is 60 degrees.

Step-by-step explanation:

If the size of the slices is proportional to the ages of the children eating the cake, then the sum of their ages equal to 360 degrees (since the cake is a circle).

So to work out the angle of Ann's portion, we find a fraction for Ann's age over the total of all of their ages. So:

5/(5 + 10 + 15) = 5/30

Now since we know their ages are proportional to the slices of cake, we can find the same value for the fraction 5/30 that is out of 360 to work out the angle. Let's call the angle representing Ann's slice x. So know we can create an equation:

5/30 = x/ 360

5/30 * 360 = x

x = 60

raketka [301]

Answer:

the hypotenuse of the given triangle is 48.5 ft

Step-by-step explanation:

the ways to detect the hypotenuse of a triangle are :

  • longest side of a right angled triangle is the hypotenuse of the triangle .
  • side opposite to the right angle ( 90° ) is the hypotenuse of the right angled triangle .

<em> </em><em>in</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>figure</em><em> </em><em>the</em><em> </em><em>longest</em><em> </em><em>side</em><em> </em><em>is</em><em> </em><em>48</em><em>.</em><em>5</em><em>,</em><em> </em><em>hence</em><em> </em><em>it's</em><em> </em><em>the</em><em> </em><em>hypotenuse</em><em>.</em><em>.</em><em>.</em><em>.</em>

Use suitable identities to find the following products (x+4)(x+10)​
Anestetic [448]

Answer:

x^2 + 14x + 40

Step-by-step explanation:

Here we gonna use the identity -

(x+a)(x+b) = x^2+(a+b)x + ab

So  using the identity here,

(x+4)(x+10) \\=> x^2 +(4+10)x+4*10\\=>x^2+14x+40
