Three consecutive odd numbers have a sum of 45. what is the greatest number?

rodikova [14]

Let's assume the middle number is $x$
then the smallest number is $x-2$
the greatest number is $x+2$
so the sum of the three number would be $(x-2)+x+(x+2)$ and it equals 45
now we have an equation $(x-2)+x+(x+2)=45$
then we solve it $3x=45$
$x=15$ , which means the middle number equals 15
so the greatest number would be $x+2=15+2=17$
17 is the greatest number

Help plz 13. Mildred is flying a kite on a 30 m string. The angle of elevation of the kite measures 40 degrees,

scoray [572]

Answer: 21.3m

Step-by-step explanation:

The height of the kite of the ground would be calculated as:

We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.

Therefore, the height of the kite would be:

= 30 sin 40 + 2

= 30 (0.6428 ) + 2

= 19.284 + 2

= 21.284 m

= 21.3 m
