Explanation:
1. ∠BAC ≅ ∠BCA, BD ≅ BE, ∆BDA and ∆BEC are right triangles . . . . given
2. ∆ABC is isosceles . . . . definition of isosceles triangle
3. BA ≅ BC . . . . definition of isosceles triangle
4. ∆BDA ≅ ∆BEC . . . . HL theorem
5. AC ≅ CE . . . . CPCTC
The first one is not proportional and the second one is proportional.
Each pair of tangents to a point makes two congruent segments to the circle. So if we label all the little segments, say clockwise starting at the top, we get
27, 22, 22, 98, 98, 22, 22, 27
The sum is 338

Answer:
Step-by-step explanation:
a = 4
b= 1
c = 2
d =2
Leftside of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 4 *4 + 8 =16 + 8 = 24
No. of P molecules = 2
Right side of equation:
No. of H molecules = 4
No. of Cl molecules = 4
No. of O molecules = 2*5 + 2 *7 = 10 + 14 = 24
No. of P molecules = 2
