Question

please please please help it is very urgent please please and please show full method ​

Answer 1

Answer:

Step-by-step explanation:

Let the equal angle be x

Total sum of angle of tringle= 180

So, 2x+100=180

2x=180-100

x= 80÷2

x=40

So the measure of all the angles of tringles are 40,40,100.

Answer 2

Step-by-step explanation:

to find

measur of other two angles

according to question

one angle = 100°

2nd angle = 3rd angle

we know that the

a triangle has three sides and sum of its angles are 180

so 1st angle + 2nd angle + 100 = 180

let 1st angle be x then 2nd of them = x (coz both are equal)

so x + x + 100 = 180

2x + 100 = 180

2x = 180 - 100

x= 80/2

then x = 40

so measure of other two angles are 40 °
