Объяснение:

the side surface of this pyramid consists of 6 isosceles triangles with a base 16 and a side 17.

Find the area of one triangle.

S = 1/2bh, where b is the base and h is the height.

The height is found by the Pythagorean theorem.

The height is equal to the square root of the difference between the squares of the side of the triangle and the half of the base. Half of the base 16 / 2 = 8

17*17 - 8*8 = 225. The square root of 225 is 15. The height of the triangle is 15. Then the area of the triangle will be equal to S = 1/2*16*15 = 120 and the area of the side surface of this pyramid is equal to the area of one triangle multiplied by 6. S1 = 120 * 6 = 720

Hi andrewthank u for ur letter. im so sorry that didnt write so long, i was in bohemia. in ur last letter u writed about ur non gadget week. it is very interesting experemental project and i would like to test myself by this challange. at last time i am wasting my life in internet 3 to 5 hours a day. if i will use only one gadget, this gadget will be a smart phone. i think nowadays smart phone is the most functional gadget among all others. if i would have more free time, ill go in fitness club, because i should be more careful with my health. so, how passed ur non gadget week? have u any other experemental projects in ur school? what are u thinking about fitness club? i thing thats all for today. waiting for ur letter! best wishes, strapony (сокращения пишите полностью, ибо мне лень)
