45°
B
the sum of the angles of triangles is 180°
60°+75°+x=180°
135°+x=180°
135°-135°+x=180°-135°
x°=45

Answer:
s=31
Step-by-step explanation:
hi again so what you are gonna do is find out the opposite of subtraction which is addition then you are gonna do the opposite..so add 19 and 12 together then your sum would be 31.....to check your answer you must subtract 31 from 19 and then you get 12....so therefore s=31
hope you are getting a better understanding!
Answer:
1. PQ
2. PR
3. OR/OP
4. OR/OP
5. RO
Step-by-step explanation:
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7
In a number line its shows u were the spt of the numbers are soo. Lets say the number line goes by 2s. Its starts in 8 soo its 8, 10, 12. Go closer and its 10 , 11 , 12 . closer. 11, 11.1 , 11. 2. Untilit keeps going and u can see that 11.6 is farther to the right so that means that it is greater
