Answer: try photo math
Step-by-step explanation:
by using Pythagoras theorem c2= a2 + b2
so let's say c= 17 and a= 7, let's calculate for b
(17)^2 = (7)^2 + b2
289= 49+b2
289 - 49 = b2
240 =b2
√249 = b
b = 15 . 49
Range is f(x) < -2
* The < should have a line under it*
**Sorry i couldn't find the domain**
X=55
Equation would be x-20+x=90
90+20=110
110/2=x
Answer:
72
Step-by-step explanation:
One way to do this is to use the formula where and are the lengths of the two diagonals.
In the figure, and (2 + 10 and 6 + 6).
The area is square units.
Another way that doesn't depend on learning a formula is to remember that the diagonals of a kite are perpendicular, so the 4 small triangles are right triangles. Two of the smaller triangles have base =2 and height = 6, so their areas are 1/2(2)(6) = 6. Double that--there are 2 congruent small triangles--to get an area of 12.
There are two larger right triangles with base =10 and height = 6, so their area are 1/2(10)(6)=30. There are two of those, so their combined area is 60.
Finally, put the small triangle area and the large triangle area together to get a total of 12 + 60 = 72
