Answer:
By exterior angle theorem, we have;
∠DBE = ∠H + ∠HEB = ∠ECD = ∠H + ∠HDC
∴ ∠H + ∠HEB = ∠H + ∠HDC
By addition property of equality, we have
∠HEB = ∠HDC
∠H = ∠H by reflexive property
∴ ΔHCD ~ ΔHEB by Angle Angle AA similarity postulate
∴ HE/HD = EB/DC, by the definition of similarity
Therefore, by cross multiplication, we have;
HE × DC = EB × HD
Therefore, by commutative property of multiplication, we have;
HE × DC = HD × EB
Step-by-step explanation:
Yes because square root of 4 is 2 and square root of 16 is 4. 4+2=6
Answer:
0
Step-by-step explanation:
any numbers multiply by zero always equals to zero
8 is the angle DHL with H the vertex
The angles in a triangle add up to 180 so if we add up 35 and 45 we get 80. subtract 80 from 180 and we are left with 100. So the answer is b
