Star + triangle + triangle = 32 star + star + triangle + triangle = 56 star = () triangle = () how many stars are there, triangle

Answer: 16, △ 8,
Because [
☆+△+△ ＝32
So [+ △ = 56-32 = 24
According to: [
☆+ △ ＝24
So △ = 32-24 = 8
☆＝24－8＝16

If the height of the bottom edge of an isosceles triangle is 8 and the perimeter is 32, then the area of the triangle is ()
A. 56B. 48C. 46D. 32

Let AB = AC, ad ⊥ BC in △ ABC, then 2Ac + BC = 32, ∵ AC = 16-dc, ∵ DC2 + ad2 = ac2, ∵ CD = 6, ∵ BC = 2CD = 12, ∵ triangle area is 12 × 8 ⊥ 2 = 48
