Answer:
5/6
Step-by-step explanation:
Step-by-step explanation:
Lets assume that angle of right angle trangles are <a,<b and <c
here one of the angle is 90°
so, <a=90°
now,
By the question
<c=3×<b+14
again,
<a+<b+<c=180° (being sum of interior angles of trangles)
90°+<b+(3×<b+14)=180° ( including the value of <a and <c)
90°+<b+3<b+14=180°
4<b=180-90-14
<b=86/4
<b=19°
<c=3×<b+14
=3×19+14
<c=71
smallest angle is 19°
and another small angle is 71°
V= πr2h
V= (3.14x12mx12m)8m
V= (452.16mx8m)
V=3,617.28m^3
Answer:
15x^4z^2
Step-by-step explanation:
We need to break each term into the smallest factors
30 = 3*10 = 3*2*5
75 = 3*25 = 3*5*5
-30 x^4yz^3 = -3*2*5 * xxxxyzzz
75 x^4z^2 = 5*5*3xxxxzz
What common factors are in each term
3*5*xxxx*zz
15x^4z^2
