Answer:
107 degrees
Step-by-step explanation:
All polygon degrees add up to 360
we know that this polygon has a angle of 90 and 56
subtract 90 and 56 from 360 to get 214
Then divide by 2 because there are 2 x angles
to get 107 degrees
Answer:
Step-by-step explanation:
Insert the original values of C and D into the new expression:
Simplify the expression. Use the distributive property:
Combine like terms:
:Done
25÷100=0.25
0.25×n=the percentage
Or 0.25n
Or 0.25•n
Let’s say n=4
2(4)+1=9
(i) N can be an odd or an even number but still come out to an even number when multiplied by 2 since 2 is even. However, since an odd number is added to these positive numbers, they will result in an odd number. Therefore, 2n+1 is an odd number.
(ii)(a) 2(1)+1=3, so the next odd number is 5, so we write 2(2)+1=5
(ii)(b) Let’s use 3 and 5 since consecutive means following one another.
3+5=8 Which is the same as 4(2)=8
We can also use 9+11=20 which is the same as 4(5)
