Answer:

the answer is 27.5

Step-by-step explanation:

first you add all the like terms

7+7+17+7+7=45

then you subtract 45 from 100

100-45=55

then you know that the two varibles will equal 55 so the you divide 55 by 2

Find the slant height of the cone.
sammy [17]

Answer:

The slant height is 13m

Step-by-step explanation:

The slant height of the cone, l , can be found using Pythagoras Theorem.

l^2=12^2+(\frac{10}{2})^2

l^2=12^2+(5)^2

l^2=144+25

l^2=169

l=\sqrt{169}

l=13m

Need help with A and C <br><br>please :)
Dennis_Churaev [7]

First step: name the sides according to geometry standards, namely, the sides are named the same lowercase letter as the opposing angle. A revised diagram is shown.

Second step: we need to know the relationships of the trigonometric functions.

cosine(A)=cos(63) = adjacent / hypotenuse = AC/AB .................(1)

sine(A)=sin(63) = opposite / hypotenuse = CB/AB .......................(2)

We're given AB=7, so

using (1)

AC/AB=cos(63)

AC=ABcos(63)=7 cos(63) = 7*0.45399 = 3.17993 = 3.180 (to three dec. figures)

Using (2)

BC/AB=sin(63)

BC=ABsin(63) = 7 sin(63) = 7*0.89101 = 6.237 (to three dec. figures).
