A. Find the length of the midsegment of an equilateral triangle with side lengths of 12.5 cm.

pantera1 [17]

Answer:

a. 6.25
b. AT = 33
c. y = 3

Step-by-step explanation:

a. Midsegment is half the length of the parallel side:

12.5/2 = 6.25

b. Segment addition postulate:

AB = AT + TB = 3x + 6 + 42 - x = 2x + 48

Perpendicular bisector of segment divides the segment in two equal halves:

AT = TB
3x + 6 = 42 - x
4x = 36
x = 9

AT is:

AT = 3*9 + 6
= 33

c) The point on the angle bisector H is equidistant from the point E and G:

EH = HG
5y + 10 = 28 - y
5y + y = 28 - 10
6y = 18
y = 3

The components of vector are ax and ay (both positive), and the angle that it makes with respect to the positive x axis is θ. Fi

Andru [333]

we can use formula

$\theta=tan^{-1}(\frac{a_y}{a_x})$

(a)

we are given

$a_x=12,a_y=12$

now, we can plug values

$\theta=tan^{-1}(\frac{12}{12})$

$\theta=tan^{-1}(1)$

$\theta=\frac{\pi}{4}rad$

(b)

we are given

$a_x=20,a_y=12$

now, we can plug values

$\theta=tan^{-1}(\frac{12}{20})$

$\theta=tan^{-1}(\frac{3}{5})$

$\theta=30.96^{\circ \:}$

(c)

we are given

$a_x=12,a_y=20$

now, we can plug values

$\theta=tan^{-1}(\frac{20}{12})$

$\theta=tan^{-1}(\frac{5}{3})$

$\theta=59.03^{\circ \:}$
