If x-10=15 and x=25
then the Hypothesis would be true.
25-10=15
the answer if those two are the answers it'd be A.
Answer: -3
Step-by-step explanation:
<em>h ≈ 0.25 cm</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
- <u><em>density formula</em></u>
<em>d = m/V</em>
<em>V = l×w×h</em>
<em>replace</em>
<em>2.17 = 438/(40×20)×h</em>
<em>2.17 = 438/800×h</em>
<em>2.17×800×h = 438</em>
<em>1736h = 438</em>
<em>h = 438/1736</em>
<em>h ≈ 0,25 cm</em>
<em>Good luck !</em>

Answer:
Step-by-step explanation:
4 g.
c=42
a=b=d
a+b+42=180
a+a=180-42
2a=138
a=138/2=69
a=69
b=69
c=42
d=69
5a.
a=30
angle O=180-(a+30)=180-(30+30)=180-60=120°
d=80
angle O=180-(d+80))=180-(80+80)=180-160=20°
central angle O of middle triangle=180-(120+20)=180-140=40°
b=c
b+c+40=180
b+b=180-40
2b=140
b=140/2=70
b=70°
c=70°
Answer:
8
