Answer: The answer is 25
Step-by-step explanation:
First, You would add the two numbers together, which you get 155
Then, the degrees of a triangle is equal to 180. So you would subtract 155 from 189, and you should get 55.

Answer:
answer is y^2-6y+9
Step-by-step explanation:
first take out the value of x from equation 1 which is x=(2-y)
then put the value of x in equation 2 u will get ur answer as y^2-6y+9
2/5=4/10=12/30 1/3=10/30 12/30+10/30=22/30 22/30=11/15
Answer:
12
Step-by-step explanation:
The given geometric series is

We want to determine the first term of this geometric series.
Recall that the explicit formula is

To find the first term, we put n=1 to get:

This gives us:


Therefore the first term is 12
<em>48.25 in^2</em>
Step-by-step explanation:
The formula for the surface area of a pyramid is:

B represents the area of the base, which in this case is a triangle. We will figure out the area of the base first, using the formula for the area of a triangle.


A = 10.75
Now we can plug in 10.75 for B.

The cursive L will be the lateral height, which is 5. Since there are 3 sides on the base we can put that in for the number of base sides, and the base is 5.

48.25 in^2
