The sum of the interior angle measures is 180°. Find the value of X.

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

By the Triangle Angle-Sum Theorem, the angles of a triangle add up to equal 180, regardless of the size of the triangle. We are given the angle measures, so adding them together and setting them equal to 180 is

60 + 3x + x + 20 = 180 and, combining like terms,

4x + 80 = 180. Subtracting 80 from both sides,

4x = 100 so

x = 25

Find the 15th term in the Arithmetic Sequence An = 3n-7 Question 1 options: a32 b 7 c 38 d -2 please help

Answers

we have that

$An=3n-7$

to calculate the 15th term in the Arithmetic Sequence

substitute the value of n for n=15 in the formula above

$A(15)=3*15-7$

$A(15)=45-7$

$A(15)=38$

therefore

the answer is the option C

$38$

A(15) = 3(15)-7 = 45-7 = 38.

SO, (C)38 IS THE ANSWER.
