Answer:
100 degrees
Step-by-step explanation:
Since triangle ABC is similar to triangle DEF, their angles are basically the same.
All angles of a triangle have to add up to 180.
We are already given two angles: 30 and 50
Add them together: 30 + 50 = 80
Now we subtract the number from 180
180 - 80 = 100
The remaining angle has to be 100 degrees
Answer:
A.
Step-by-step explanation:
Anwer A has the following equation:

In this equation, we can calculated the intercept replacing x by 0, as:

if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.
Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:

It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.
So, the answer is A, 
Answer:
Step-by-step explanation:
To find the volume of this solid, multiply the base area by the height:
V = (25 cm²)(4 cm) = 100 cm³
Answer:
120 square centimeters
Step-by-step explanation:
The question says the formula already.
Area = bh
b = base length b = 10
h = height length h = 12
Area = 10 · 12
Area = 120 square centimeters
Yes 2/4 is 1/2 because if you have a pie and you cut it in four pieces then you eat to you only got two pieces left so there you only have half a pie left.
