As per midsegment theorem of a trapezoid,

Segment joining the midpoints of the legs of the of the trapezoid is parallel to the bases and measure half of their sum.

Length of midsegment = $\frac{1}{2}(b_1+b_2)$

3). MN = $\frac{1}{2}(18+10)$

= 14

4). MN = $\frac{1}{2}(57+76)$

= 66.5

5). MN = $\frac{1}{2}(AB+DC)$

7 = $\frac{1}{2}(AB+10)$

14 = AB + 10

AB = 14 - 10

AB = 4

6). 15 = $\frac{1}{2}[(3x+2)+(2x-2)]$

30 = 5x

x = 6

Given the measures of three angles of a triangle, explain how to find the ratio of the lengths of two sides of the triangle.

pantera1 [17]

You can let the sides be a and b. You can then use the Law of Sines to create an equation relating the two sides and the angles opposite them, and finally isolate a/b.

Imagine that you need to compute e^0.4 but you have no calculator or other aid to enable you to compute it exactly, only paper a

Answer:

0.0032

Step-by-step explanation:

We need to compute $e^{0.4}$ by the help of third-degree Taylor polynomial that is expanded around at x = 0.

Given :

$e^{0.4}$ < e < 3

Therefore, the Taylor's Error Bound formula is given by :

$|\text{Error}| \leq \frac{M}{(N+1)!} |x-a|^{N+1}$ , where $M=|F^{N+1}(x)|$

$\leq \frac{3}{(3+1)!} |-0.4|^4$

$\leq \frac{3}{24} \times (0.4)^4$

$\leq 0.0032$

Therefore, |Error| ≤ 0.0032
