First you have to find a and c then add them all up
Answer:
41
Step-by-step explanation:
n+(-16)=25
n-16=25
Add 16 to both sides to isolate the variable
n=41
The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).
So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).
Hope this Helps!!
Answer:
2520cm²
Step-by-step explanation:
Surface area = sum of the area of all the bases.
Area of bottom base = 28 * 30 = 840
Area of right base = 25 * 30 = 750
Area of left base = 17 * 30 = 510
Area of two triangles = ( 15 * 28 ) / 2 = 210 * 2 = 420
Then add all the areas together to find surface area
Surface area = 840 + 750 + 510 + 420 = 2520cm²
Relevant Formulas:
Area of a rectangle = length * width. This formula was used to find the area of the bottom base, the right base and the left base
Area of a triangle = ( height * base length ) / 2 . This formula was used to find the area of the sides which are triangles.
Answer:
√1
Step-by-step explanation:
If you do the fractions by squaring them then you get fractions that equal 1:
5/13^2 = 25/169
12/13^2 = 144/169
144/169 + 25/169 = 169/169 = 1
√1
