Question

AOB is a line . Determine angle BOC angle COD and angle AOD.​

Answer 1

Answer:

As, AOB is a straight line.

Sum of angles on a straight line always measure 180°

So,

(2x-7)°+(2x-8)°+(x-10) = 180° [Linear angles]

5x-25 = 180°

5x = 180°+25

x = 205/5

x = 41°...

Substitute 41° in the place of x and find the values...

Answer 2

Answer:

$because \: aob \: is \: a \: line$

$and \: we \: know \: that \: straight \: line \: is$

$of \: {180}^{.}$

$so. \: boc + cod + aod = {180}^{.}$

$(x - 10) + (2x - 8) + (2x - 7) = {180}^{.}$

$(x - 10 + 2x - 8 + 2x - 7) = {180}^{.}$

$(5x - 25) = {180}^{.}$

$5x = 180 + 25$

$5x = 205$

$x = \frac{205}{5}$

$x = 41$

$now \: angle \: aod = 2x - 7$

$aod = (2 \times 41) - 7$

$aod = 75 \: answer$

$now \: angle \: cod = 2x - 8$

$cod = (2 \times 41) - 8$

$cod = 74 \: answer$

$now \: angle \: cob \: = x - 10$

$cob = 41 - 10$

$cob = 31 \: answer$
