A. Find the value of a. b. Find the value of the marked angles.

Step-by-step explanation:

We can see that they are vertically opposite angles so they are equal. then

6a + 10° = 3a + 55°

6a - 3a = 55° - 10°

3a = 45°

Therefore a = 15°

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
