Answer:
A
Step-by-step explanation:
8/(-2+2) is just 8/0 and anything divided by 0 is undefined
Answer:
<h3>D. The amount of rotation of one side.</h3>
Step-by-step explanation:
We need to explain the statement " What affects the size of an angle? ".
Given options are
A. The length of its sides
B. The direction of one side
C. Its orientation in space
D. The amount of rotation of one side.
The correct option would be :
<h3>D. The amount of rotation of one side.</h3>
<em>Because as the one side rotated, it makes a greater or smaller arc between the two lines. That would affects the size of an angle. </em>
Answer:
9 sqrt(2) /2 = PQ
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 45 = PQ = 9
9 sin 45 = PQ
9 sqrt(2) /2 = PQ
The correct option will be : B) 6 cm.
<u><em>Explanation</em></u>
Suppose, the width of the rectangle is 
cm.
As, the length is 6 cm longer than the width, so the length will be: 
<u>Formula for the Area of rectangle</u> is: 
Given that, the area of a rectangle is 72 cm²
So....
Using zero-product property, we will get...
<em>(Negative value is ignored as width can't be negative)</em>
and
So, the width of the rectangle is 6 cm.
Triangle area formula: base*height/2
so, 14*10/2 = 7*10 = 70 sq. in.
