Question

Find x
pls send me the step by step explanation. fast plzzzz​. and I need the steps it is very important

Answer 1

Answer:

35

Step-by-step explanation:

2x-5+3x+10=180

5(x+1)=180

x+1=36

x=35

Answer 2

Step-by-step explanation:

(2x-5)+ (3x+10) =180(supplementary angle and linear pair

2x+3x-5+10=180

5x+5=180

5x=180-5

5x=175

x=175/5

x=35

we found that x=35

So:

2x-5=(2×35)-5=70-5=65

Therefore, angle COA=65°

3x+10=(3×35)+10=105+10=115°

Therefore angle COB =115°

heyy here is your ans
