Given: a = 640, A = 70°, B = 52° in triangle ABC ; find c . Round answers to the nearest whole number. Do not use a decimal poin

telo118 [61]

Law of sines:
$\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}\\=\frac{640}{\sin 70}=\frac{c}{\sin (180-70-52)}\\\text{ then}\\c=\frac{640}{\sin 70}\sin (180-70-52)\\=577$

D is between C and E, CD = x 2 , CE = 32-2x, and DE = 12x. Find CD, DE, and CE.

Gemiola [76]

Answer:

CD = 4
DE = 24
CE = 28

Step-by-step explanation:

The segment addition theorem tells you ...

CD +DE = CE

x^2 +12x = 32 -2x

Subtract the right side to put this in standard form.

x^2 +14x -32 = 0

(x +16)(x -2) = 0

x = -16 or 2

In order for DE to have a positive length, we must have x > 0. So ...

CD = x^2 = 2^2 = 4

DE = 12x = 12(2) = 24

CE = 32 -2x = 32 -2(2) = 28

1/3x=5/12 show your work

insens350 [35]

Answer:

4/5 or 0.8

Step-by-step explanation:

1/3x = 5/12

cross multiply

(12×1) = (5×3x)

divide through by 15

x = 12/15

x = 4/5 or 0.8
