Answer:
n = 24
Step-by-step explanation:
(n + 18) and 2n are "complementary angles:" they add up to 90°.
Thus, n + 18 + 2n = 90. Combining the n terms results in 3n + 18 = 90.
Then 3n = 72. Dividing both sides by 3 results in n = 24.
n is 24, so n + 18 is 42 and 2n is 48. Note that 42 and 48 add up to 90.

Answer:
The coordinates of the other end is 
Step-by-step explanation:
Given
Required
Find the coordinates of the other end
Let Midpoint be represented by (x,y);
(x,y) = (5,2) is calculated as thus
So
and 
Where 
and 
So, we're solving for 
Solving for 
Substitute 5 for x and -6 for x₁
Multiply both sides by 2
Add 6 to both sides
Solving for 
Substitute 2 for y and 2 for y₁
Multiply both sides by 2
Subtract 2 from both sides
Hence, the coordinates of the other end is
The answer you are looking for is -17/44
Answer:
squaare root of 70<pi squared<10
Step-by-step explanation:
Talking about square root of 70, you can take the answer by approximation. u know square of eight is sixty four and square of nine is eighty one. so 70's square root shluld be between eight and nine. And as the value of pi is 3.14... when square of pi is considerd it should be >9 but <10 as pi>3. So 10 become te greatest
