Step-by-step explanation:
In a right angle triangle one angle is 90°
w.k.t sum of angles in a triangle is 180°
thus, 2x+15+x+90°=180°
3x+105°=180°
3x=75°
x= 75/3=25°
Hope this helps you.
Answer:
C
Step-by-step explanation:
a straight line is 180, 180-40=140
Answer:
The answer is Point N
Step-by-step explanation:
Nothing more
First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.
2x+7=3x-7
x=14
Then, since 2x+7 and 12y+1 equals 180, put it together to find y:
(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12
So, x=14 and y=12. Your answer should be C!
