Answer:
area of whole triangle is 3
area of triangle cut in half is 1.5
Step-by-step explanation:
Area: (.5)(8)(3/4)=3
Area of each triangle. It would be split down the middle. from a to c
3/2=1.5
Answer:
a(n) = a(n - 1) - 4, with a(1) = 19
Step-by-step explanation:
If the rule for finding each new term is "take away 4," then this is an arithmetic sequence with first term a(1) (unknown) and third term 11. The "common difference" is -4.
Then the formula for this arithmetic sequence is found as follows:
The third term is 11. The previous (second) term is 4 greater, or 15. The first term (coming before 15) is 19.
Thus, the general formula is
a(n) = a(n - 1) - 4, with a(1) = 19
Check: Does a(1) come out to 19? Is 19 - 4(1 - 1) = 19? YES
Does a(2) come out to 15? Is 19 - 4 = 15? YES
Does a(3) come out to 11? Is 15 - 4 = 11? YES
★ Important points to know
- The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
★ Let's solve :-
Hence option A 95⁰ is the right ans ✓
