Answer:

7 19/20 = 7.95

Step-by-step explanation:

I assume you mean 4+6/5 + 2+3/4

Commutative property

4+2+6/5+3/4

Associative property

(4+2)+(6/5+3/4) = 6 + (6/5+3/4)

Multiply by 1

6/5*4/4 +3/4*5/5

24/20+15/20

39/20+6 = 6+1+19/20 = 7+19/20

In ΔABC, m∠ACB = 90°, CD ⊥ AB and m∠ACD = 45°. Find: CD, if BC = 3 in
IRISSAK [1]
We can find m∠BCD like follows: m∠BCD=90°-45°=45<span>°
Now, m</span><span>∠DBC= 180°-(90°+45°)=45°

Remember that </span>sin \alpha = \frac{opposite leg}{hypotenuse}, so oppositeleg=(hypotenuse)(sin \alpha )

We know that hypotenuse= BC= 3in and \alpha=∠DBC)=45°, so replacing the values we get:
CD=3sin(45)=2.12

We can conclude that the segment CD is 2.12 in
