Answer:
3. 160
4. 105
5. 95
6. 30
7. 86
8. 130
All triangles equal 180 so when you add the other 2 degrees in the triangle then subtract that by 180 then you get the third angle. The a straight line also equals 180 degrees so when you get the third angle subtract it by 180 then you get the answer to the "?"
That's how I was taught so, hope I got it all right! : )
Answer:
tq eddy porada for eddy ame
Answer:

Step-by-step explanation:
Given
P(A or B)= P(B)-P(A and B)
P(A)=1/3
P(A and B)=1/8
P(A or B)= 3/4
Required
Find P(B)
To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.
This goes thus;
P(A or B) = P(B) - P(A and B) becomes

Make P(B) the subject of formula

Take L.C.M

Add fractions

From the workings above, the value of P(B) using the given equation is 
Answer:
x > 8
Step-by-step explanation:
Given
17 < 9 + x ( subtract 9 from both sides )
8 < x , hence
x > 8
