Answer:
x= 70
Step-by-step explanation:
In this question you have to use BODMAS. This indicates that you have to do the equation in the brackets first. Therefore, 3x15= 45. Then you add 25, which will give you 70.
x=70
How I got it:
3X15=45
45+25=70
it
it is C hope this helps
x = 129
x and 51 are same- side exterior angles and supplementary, thus
x = 180 - 51 = 129
m = -5
1/5 m = -1
Multiply each side by 5
5*1/5 m = -1*5
