Answer:
x ≈ 11.7
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° = = ( multiply both sides by 13 )
13 × cos26° = x , then
x ≈ 11.7 ( to the nearest tenth )
Base=18
Step-by-step explanation:
I have used area equals to base times height that's the formula of a parallelogram and I've gotten that base equals to 18 hope this helps.
The first term is 2 and the common ratio = -8/2 = -4
S7 = 2 * (-4)^7 - 1
------------- = 6554 answer
-4-1
True, for a contrapositive you switch the parts and then make them opposite, but the statement is still true.
