Answer:
Area of an isosceles right triangle is 24.5
Step-by-step explanation:
Given that triangle is an isosceles right angle which means that two side of the triangle are equal and one of the angle is .
Consider triangle (Refer to attachment),
.
Since both sides are equal angle opposite to both sides are same.
Now applying pythagoras theorem to ,
Assume ,
Substituting the value,
Simplifying,
Dividing by 2,
Taking square root on both sides,
Formula for area of triangle is given as,
Now AB=height,BC=base.
Substituting the value,
So, area of an isosceles right triangle is 24.5
Answer:
You need to buy 12 books to get a $15 coupon.
Step-by-step explanation:
Giving the following information:
You get a $5 coupon for every 4 books you buy.
<u>First, we need to structure the total coupon formula:</u>
Total coupon= 5*x
x= pack of four books
<u>Now, for $15</u>
15 = 5x
15/5= x
3= x
4*3= 12
You need to buy 12 books to get a $15 coupon.
The interquartile range is 24.5
the variability is 69
I believe the correct answer from the choices listed above is option C. <span>If two lines are parallel, their slopes are equal. Having equal slopes mean that the rise and run of the points of the lines are the same. Parallel lines do not intersect even when extended infinitely.</span>
