Answer:
7:5
Step-by-step explanation:
49/7 = 7 and 35/7 = 5
to get a ratio, divide both side by the same number that is a facttor for both.
Given:
A right angle triangle with angles 45, 45, 90 degrees.
Hypotenuse of the triangle = 
mm
Base of the triangle = t
To find:
The value of t.
Solution:
In a right angle triangle,
Using this trigonometric ratio in the given triangle, we get
Therefore, the value of t is 7 millimetres.
Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
