How do i get A and B ?

a=60°

b=300°

Step-by-step explanation:

the triangle is equilateral so all angles are 60 °

a = 60°

b=360 - 60 =300°

A is 60°, B is 300°

Step-by-step explanation:

If you look closely, you can tell that this circle is divided into 6 triangles, but there is only one showing. This triangle is 1/6 of the circle.

You can find B by find 1/6 of 360° and subtracting that from 360, (a full circle is 360°)

1/6 of 360° is 60°

360° - 60° = 300°, so B is 300°

Now lets find A. Triangles are 180°. This triangle is obviously an equilateral triangle, so the measurements will all be the same.

180 ÷ 3 is 60, so A is 60°

I hope this helped, please mark Brainliest, thank you!

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
