Step-by-step explanation:
For no. 11
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 4
Also,
4y + 7 ° + 10y - 37° = 180° { being co-interior angles }
14y - 30° = 180°
14y = 210°
y = 210° / 14
y = 15°
For no. 12
5x + 38° = 8x - 19° { being opposite angles of parallelogram }
8x - 5x = 38° + 19°
3x = 57°
x = 19°
Hope it will help :)
Answer:
So the expression in simplified radical form will be
Step-by-step explanation:
We have have given the expression
We have to write this expression in simplest radical form
For writing in simplest radical form we have to rationalize first
So after rationalizing
So the expression in simplified radical form will be
8/9 x = 32
x = (32 * 9)/8 = 4 * 9 = 36
x = 36
The highest common factor is 7:
49=7*7
84=7*12
91=7*13
