Answer:
Given: In ΔABC ,
To prove that:
[Given]
In ΔADB
The sine angle is defined in the context of a right triangle is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle.
[By definition of sine] .....[1]
Multiplication Property of equality states that you multiply both sides of an equation by the same number.
Multiply by c to both sides of an equation [1] we get;
Simplify:
......[2]
Now, In ΔACD
Using definition of sine:
Multiply both sides of an equation by b;
[Multiplication Property of equality]
Simplify:
......[3]
Substitute [3] in [2];
......[4]
Division property of equality states that if you divide both sides of an equation by the same nonzero number the sides remains equal.
[4] ⇒
Therefore, the missing statement in step 6 is;
All times. The numbers you are dividing with are quotients.
1 and 3/4 cups = 4/4 + 3/4 = 7/4 cups This equals 1 batch. If we want 2.5 batches, then we multiply by 2.5 2.5 x 7/4 = x 4.375 cups = x You can also add the cups one batch and then a half batch at a time. 7/4 + 7/4 + (7/4*1/2) = x multiply the first two (7/4) by 2/2 so there is a common denominator of 8 Then you have 14/8 + 14/8 + 7/8 = 35/8 = 4.375 cups
Answer:
14√2
Step-by-step explanation:
Using 45 45 90 triangle properties,
b = 28/√2 = 14√2
The algebraic property is called here commutativity :
<span>x ⋅ y ⋅ z = y ⋅ x ⋅ z
| ÷z (We divide by z)
</span>
→ x ⋅ y = y ⋅ x → <span>That means you can switch ( = commute) factors anyway, the product will remain the same.</span>
