Question

if (y-25)and (y+35) form a linear pair then the measure of the angels are :

(a) 20,160
(b) 110,70
(c) 60,120
(d) 150,30​

Answer 1

Answer:

60,120

Step-by-step explanation:

*

$(y - 25) + (y + 35) = 180 \\ 2y - 25 + 35 = 180 \\ 2y - 25 = 180 - 35 \\ 2y = 180 - 35 + 25 \\ 2y = 180 - 10 \\ y = 180 - 10 \div 2 \\ y = 85 \\ so(y - 25) = 60 \\ (y + 35) = 120$
