X= A) 80 I believe you double 120 to 240 and divide by the 4 quarters.
Hey there!
The answer would be 4 FEET. If the slide is 10 feet tall and you are 6 feet down the slide then your are only 4 feet high. Just simple subtraction! So x = 4.
Hope this helps!
Answer:
121°
Step-by-step explanation:
<B = 9x - 5°
<D = 10x - 19°
<B = <D ( being opposite angles of parallelogram)
9x - 5° = 10x - 19°
10x - 9x = 19° - 5°
x = 14°
Now
<B = 9x - 5°
= 9 * 14° - 5
= 121°
