1. You will have to find the height first which could be done by using pythagoras theorem
split the 12 by half giving 6
a^2 = b^2 + c^2
13^2 = 6^2+c^2
169 = 36+c^2
c^2=169-36
c^2=133
c=sqrt133
c= 11.53
area of triangle
1/2 x b x h
1/2 x 6 x 11.53
34.59
34.5(3 sf)
10P8 = 10!/(10 - 8)! = 10!/2! = 1,814,400
Answer:
Step-by-step explanation:
Hope this helps!
Answer:
I believe your rule would be (The rule is add 3)
Step-by-step explanation:
If you have -9 and you get to -6 that means you added an interval of 3
-9,-6,-3,0,3 is how it would continue
(The rule is add 3)
Sin230=sin(180+50)=sin180cos50+cos180sin50=-sin50 answer 1
