I need help with this question, pls put step by step ​

Answer:

150 degrees and 30 degrees

Step-by-step explanation:

Let's say the measure of the angle is x. This angle is 5 times that of its supplementary, supplementary angles will add up to 180 degrees. So we have an equation of x = 5(180-x). Solve this equation for x

x = 5(180-x)

x = 900 - 5x

6x = 900

x = 150 degrees, this is the value of one angle

The other angle is 180-x = 180-150 = 30 degrees

Answer:(a) Co-ordinate rule is  and  

(b) Co-ordinates of B' and C' are  and  respectively.

Step-by-step explanation:

(a)

Here, the co-ordinates of A are translated to A'.

For the co-ordinates A and A',   and  

So, x value of A has shifted to right by 6 units and y value of A has shifted 8 units down.

Hence, the co-ordinate rule that maps ΔABC onto ΔA'B'C' is:

and .

(b)

Using the co-ordinate rule, we can find the co-ordinates of B' and C'.

For B,  and .

So,  of B' is  

And,  of B' is .

Therefore, co-ordinates of B' are .

For C,  and .

So,  of C' is  

And,  of C' is .

Therefore, co-ordinates of C' are .
