ABC ia an isosceles triangle AB=AC and angle A=53° the length of side, a=12.5cm. Calculate the altitude of the triangle correct to 2s. f.

area of traingle=1/2(sin130×AB×AC)

85×3=sin130×AB×AB

255=76×AB²

255/76=AB²

√332.88=AB

AB=18.24

AC=18.24

Step-by-step explanation:

Hope this helps.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
