Find the area of the triangle below.

Mathematics
1 answer:
myrzilka [38]3 years ago
6 0

Answer:

20

Step-by-step explanation:

Since this is not a right angle, we can use the formula Area= Sin(y) (\frac{1}{2}ab)

a=7

b=10

y=35

So, when we plug these values in, we get:

a=Sin(35)(\frac{(10)(7)}{2})\\\\=35sin(35)\\=20.075\\

rounded to the nearest hundredth, I believe it's 20.

Consider the sequence {4,6,8,10,...} find the 130th term of the sequence
Olin [163]

262

Step-by-step explanation:

Step 1:

To find the nth term of a sequence the basic formula is

Sn = (n*d) + (a-d)

Whereas

Sn= nth Term

n= Term to be found

d= Difference between the terms in the sequence

a= First term in the sequence

Step 2:

Sn = (130*2) +(4-2)

= 260+2

Sn= 262

The nth term for the given problem is 262
