An exterior angle of a triangle is 140 degrees. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?

Answers

The measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees

Solution:

Given that exterior angle of triangle is 140 degrees

The exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles

Given that adjacent angles are congruent

Let one of the non adjacent interior angles be "x"

x + x = 140

2x = 140

x = 70

So the two interior angles are 70 degrees and 70 degrees

Let us find the third interior angle

The angle sum property of a triangle states that the interior angles of a triangle always add up to 180 degrees

70 + 70 + third angle = 180

third angle = 180 - 70 - 70

third angle = 180 - 140

third angle = 40 degrees

Thus the measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees

How do i solve -6+2(-2+8v-6v)

Answers

you can simplfy but not solve

distributive preopotty
a(b+c)=ab+ac

fist simlify all inside parenthasees
-2+8v-6v
-2+2v

now we have
-6+2(-2+2v)
distribute
2(-2+2v)=2*-2+2*2v=-4+4v

now we have

-6-4+4v
-10+4v is simplfied form

Two students share 3 granola bars equally. How many granola bars does each student get?

Answers

Answer:

Hence, number of granola bars each get:

1.5 bars

Step-by-step explanation:

It is given that:

Two students share 3 granola bars equally.

This means that 3 bars is to be distributed among 2 students.

Number of students=2.

Number of bars=3.

Hence,

Number\ of\ quantity\ each\ get=(Number\ of\ granola\ bars)/(Number\ of\ students)

Hence,

Number\ of\ quantity\ each\ get=(3)/(2)=1.5

Hence, number of granola bars each get:

1.5 bars
Each student receives one and a half granola bars.

4 pages in 6 minutes. how long to read 6 pages

Answers

if you read 4 pages in 6 minutes, that means you read 2/3 of a page each minute. if you need to read 6 pages, then you divide 6 by 2/3 to get 9 minutes. 
If you read 4 pages in 6 minutes, you divide 4 by 6=  1 minute and 50 seconds per page. 1.50 × 6 would give you ( 9 minutes to read 6 pages )
