Answer:

<c =60

Step-by-step explanation:

The angles of a triangle need to add up to 180 degrees. if you subtract 40 and 80 from 180 you will come up with the answer 60

Answer : The correct option is, (B) 60^o

Step-by-step explanation :

As we are given a triangle ABC.

Given:

\angle A=40^o

\angle B=80^o

Property of triangle : The sum of the interior angle of a triangle is equal to 180^o

That means,

\angle A+\angle B+\angle C=180^o

Now put all the value of angle in this expression, we get:

40^o+80^o+\angle C=180^o

120^o+\angle C=180^o

\angle C=180^o-120^o

\angle C=60^o

Therefore, the value of \angle C is, 60^o

What is the domain of the function
Ksenya-84 [330]

Answer:

x\geq -6

Step-by-step explanation:

The domain of a function is all of the values that x can be under that specific function. In this case, we're asking what values of x allow \sqrt{\frac{1}{3} x+2} to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to 0, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for x:

\frac{1}{3}x+2\geq 0

Solving this inequality, we get:

\frac{1}{3}x+2\geq 0

\frac{1}{3}x\geq -2 (Subtract 2 from both sides of the inequality to isolate x)

x\geq -6 (Multiply both sides of the inequality by 3 to get rid of x's coefficient)

Hope this helps!

Classify the triangle by its angles.
dedylja [7]

Answer:

29°: Acute 90°: Right 61°: Acute

Step-by-step explanation:

If an angle is less than 90 degrees, it is acute. If it is greater than 90 degrees, it is obtuse. If it is exactly 90 degrees, it is right.
