Answer:
r = 55°, s = 25°, t = 30°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the 4 angles in the top quadrilateral and equate to 360
r + 100° + 110° + 95° = 360°
r + 305° = 360° ( subtract 305° from both sides )
r = 55°
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180° in the left triangle for s
s = 180° - (100 + 55)° = 180° - 155° = 25°
Similarly for the triangle on the right for t
t = 180° - 95 + 55)° = 180° - 150° = 30°
Answer:

Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example

and

ARE Conjugates.
The conjugate of

is

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be

We can apply the difference of squares for the denominator.

So our denominator will be

So our rationalized fraction will be
