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

-2=3(y-2) how do you solve this problem for y​
Ksivusya [100]

Answer:

y= 4/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2=3(y−2)

−2=(3)(y)+(3)(−2)(Distribute)

−2=3y+−6

−2=3y−6

Step 2: Flip the equation.

3y−6=−2

Step 3: Add 6 to both sides.

3y−6+6=−2+6

3y=4

Step 4: Divide both sides by 3.

3y /3 = 4 /3

y= 4/3

Answer:

y= 4/3

An arithmetic sequence has this recursive formula:
horsena [70]

Answer:

\text{\bf{C.}}\quad a_n=4+(n-1)(-7)

Step-by-step explanation:

An arithmetic sequence that is described by the explicit formula ...

  a_n=a_1+(n-1)d

can also be described by the recursive formula ...

  \left \{\begin{array}{l}a_1=\text{(first term)}&a_n=a_{n-1}+d&\end{array}\right.

Matching parts of the formulas, we see that a1 = 4, d = -7. Putting these values into the explicit formula gives ...

a_n=4+(n-1)(-7)
