Answer: 9/x-1
Step-by-step explanation:
Sine you are subtracting,
x-x=o
1- -8 =9 since subtracting a negative is adding a positive.
So the answer is 9/x-1
Ok, to prove the two triangles, we need reasoning:
1) the side AC is common (as you can see, both triangles share the side AC)
2) angle DCA is equal to angle BAC (this is due to alternate angles)
3) angle BCA is equal to angle DA (again, this is due to alternate angles)
Answer:
option 2
Step-by-step explanation:
The problem can be solved using Pythagoras' identity for a right triangle.
The angle between due East and due North is 90°
The solution here involves using the Cosine rule.
let x be the direct distance between house and office, then
x² = 17² + 21² - 2(17)(21)cos90° → option 2
Note that since cos90° = 0 the equation reduces to
x² = 17² + 21² ← Pythagoras' identity
Well you could round it to the 4th decimal, which would be 2.7183
That as a mixed number would be
Answer:
$8,961 is your answer.
Step-by-step explanation:
What you do is multiply.
<em>15,450 x 14% = 2,163</em>
<em>2,163 x 3 = $6,489</em>
<em>$15,450 - $6,489 = $8,961</em>
$8,961 is your answer.
