x = 70°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an external angle of the triangle, thus
x + 50 = 120 ( subtract 50 from both sides )
x = 70
Answer:
A third degree binomial
Step-by-step explanation:
The highest power is 3 hence the 3rd degree
and there are 2 terms hence the bi-nomial
Answer:

Step-by-step explanation:
Here we are given four equations and we have to find the equation that gives the number of half inches that are in
inches.
To find how many half inches i.e.
inches are there in
inches we have to divide
by
.
So, the equation that will give the result is
(Answer)
Answer:
-1
Step-by-step explanation:
Square root 1 is 1. Add that to the 12 to get 13. Subtract 13 from both sides to get: -5x = 5. Divide both sides by -5 to get your answer: -1
5(n) - 2 = 3
3 · 9(m) =27
1. is 27
3^2(s)= 9 · 5(t) = 45 · 2(r) = 90
2. is 90
