Question

find angle AOC and angle BOC from this figue AOIOB​

Answer 1

Answer:

2x - 5 + x-10 =90

3x-15 =90

x - 5 = 30

x= 5

Angle AOC = 5°

Angel BOC =

Step-by-step explanation:

SINCE AO IS PERPENDICULAR ON OB

SO , Angel AOB = 90°

Answer 2

AO is parallel to OB, so angle AOB measures 90°.

Therefore,

$(2x - 5) \degree + (x - 10) \degree = 90 \degree$

$\implies 3x - 15 = 90 \degree$

$\implies 3x = 105 \degree$

$\implies x = 35 \degree$

Therefore,

$\angle AOC = (2 \times 35 - 5) \degree$

$= 65 \degree$

$\angle BOC =(35 - 10) \degree$

$= 25 \degree$
