Question

i)
There are nine angles at a point. One of them is 40° and all the other eight angles are equal.
What is the measure of each of those equal angles?​

Answer 1

Answer:

if there are nine angles and one measures 40°

then 360°-40°

320°

now 320°/8

40° each

Answer 2

Answer:

40°

Step-by-step explanation:

all 9 angles will sum up to 360°

therefore,

the sum of all 8 equal angles is 360° - 40° = 320°

Now, as all the rest of the angles are equal,

let the value of each angle be y. Then,

8 x y = 320°

y = 320°/8

y = 40°
