X= 10. Should be pretty easy
<span>Triangle ABC is congruent to triangle DEF
</span>m<A = m<span><D
</span>m<B = m<span><E
</span>m<C = m<span><F
AB = DE
BC = EF
AC = DF
So answer:
</span>m∠C=m∠F
Answer:
i don't know because of the picture not showing.
Step-by-step explanation:
Yes you have the right idea. You find the derivative to get the velocity function and then determine when the velocity is zero. That turns out to be at t = 2 and t = 6. Both are correct. The final answer is correct.
The only flaw I see is that you wrote
x'(t) = 3y^3 - 24t + 36
on line 2 when it should be
x'(t) = 3t^2 - 24t + 36
Other than that it looks perfect.
Answer:
BC = 23
Step-by-step explanation:
Since ∠ A = ∠ C then the triangle is isosceles with AB = BC, that is
3x + 14 = x + 20 ( subtract x from both sides )
2x + 14 = 20 ( subtract 14 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
BC = 3x + 14 = 3(3) + 14 = 9 + 14 = 23
