Simplify. 1/3(21.69−24.99) enter your answer, as a decimal to tenths, in the box.

-1.1

Step-by-step explanation:

The given expression : -

To simplify the above given expression , we follow BODMAS (Bracket → Of → Diviide→ Multiply→ Add→ Subtract (A series of operation to perform )).

First we simplify the problem inside the bracket , we get

Now, open Parenthesis or bracket , we get

Therefore, the final answer is -1.1 .

D : 125°,125°,55°,55°

Step-by-step explanation:

Finding the interior angles makes the question easier.

The two base angles for b1 are both 125°, and the two base angles for b2 are both 55°.

Because a straight line is 180°, we can find the exterior angles by subtracting the interior angles from 180°.

180°-55° = 125°

180°-125° = 55°
