Fine the value of the x in the triangle shown below.

Sever21 [200]

Answer:

x=28

Step-by-step explanation:

The interior angles of a triangle must add to 180 degrees

Therefore,

79+73+x=180

Combine like terms by adding 79 and 73

152+x=180

To solve for x, get x by itself. Since 152 is being added to x, subtract 152 from both sides. This will cancel the 152, and leave x by itself.

152-152+x=180-152

x=28

So, x is equal to 28 degrees

Answer: $\sum_{n=1}^{5}4^n=1364$

Step-by-step explanation:

Since we have given that

$\sum_{n=1}^{5}4^n$

Now, we know the rule for summation , we'll apply this ,

$\sum_{n=1}^{5}4^n\\=4^1+4^2+4^3+4^4+4^5\\$

Now, it becomes geometric progression, so we us the formula for sum of terms in g.p. which is given by

$S_n=\frac{a(r^n-1)}{r-1}\\\\\text{where 'a' is the first term and 'r' is the common ratio}$

So, our equation becomes ,

$a=4 \\\\r=\frac{a_2}{a_1}=\frac{4^2}{4}=4\\\\S_5=\frac{4(4^5-1)}{4-1}\\\\S_5=1364$

Hence ,

$\sum_{n=1}^{5}4^n=1364$

Does 1/2+1/8 = to 3/4

AleksAgata [21]

1/2 is 2/4, and so we would need another 1/4 to make it equal to 3/4
1/8 is not equal to 1/4, so 1/2+1/8 does not equal 3/4
