Answer: r=(-189)
first you subtract both sides by 8 and get -21=r/9
then you multiply 9 with each side and get -189 = r
you can check by rewriting the problem with -189 as r and solving the equation
Answer:
Obviously condensation
Step-by-step explanation: because it is
Step-by-step explanation:
We are given with the two sides of a right angled triangle having lengths of 5 and 13. It is required to find the length of the third side of a right triangle. We know that hypotenuse of right angled triangle is the longest side.
For right angle triangle, we use Pythagoras theorem as :
H²=P²+B²
P is perpendicular distance
B is base
Putting H = 13 and P = 5, then
B² = H²-P²
B² = (13)²-(5)²
B²=144
B=12
So, the length if the third side of a right triangle is 12. It is the only solution.
| x + 4 | = 5
x + 4 = 5 x + 4 = -5
x = 5 - 4 x = -5 - 4
x = 1 x = -9
solution : x = 1 and x = -9
