d) 7(30 + 9) = 7(30) + 7(9)
Step-by-step explanation:
<u>Distributive method</u>:
<u>Here given</u>:
Among the option's:
<u>1st option</u> (7 + 3) (7 + 9) is wrong, changes <u>final answer</u>.
<u>2nd option</u> (7 × 30) + 9 is wrong, changes <u>final answer</u>.
3rd option 39 × 7 shows commutative property of multiplication.
<u>4th option</u> show distributive method.
Recall the fundamental rule of trig:
So, there exists an angle 
such that
if and only if
Working out the numbers, we get
So, there doesn't exist a number such that
Answer:
Yes, they are congruent
Step-by-step explanation:
Two figures are congruent if they have the same side lengths and the same angles, all in the same order. (I mean "same order" by you couldn't have a rectangle and a kite with different orders of the sides being congruent). Now, if we use this, we can compare the sides and angles to find out that they are indeed congruent.
