The total amount of degrees in a triangle is 180. All three angles should add up to 180˚
We know that 40+60 = 100
The next step is to do 180-100 to get the other angle.
180-100 = 80
So the measure of the third angle is 80˚
Hope this helps!
(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)
10/25 = 2/5
Divide by 5 to get simplest form
F(4-x)=12
Domain:(-oo,oo) these are infinity symbols by the way.
0.4/0.3=1.3
1.3 is the answer
You have to divide 4/10 and 1/3 and what ever two answers you get from there is the two that you divide
Answer:
38, 26
Step-by-step explanation:
(x+78) + (x-12) +x = 180
3x + 66 =180
3x = 114
x = 38
P = 38-12=26
