The answer is 21.
Explanation:
5x3=15
15+6=21
5,7 and 8 are right angles, and 6 is an acute angle this is because of u look at 9 and 10 you can see a little box looking thing under the h and if u do that to all of them 5, 7 and 8 can fit the little box but 6 you can’t because it is an acute angle. Hope this helped!
45 multiply 1/2 and 90 put it in the calculator 90 times 0.5
1.q=p-2n
2.q=75000-2*20000
q=75000-40000
q=35000
3.p=90000+2*25000
p=90000+50000
p=140000
Hope this helps :)
