2 angles in a tringle add up to 115 degrees what is the size of the thrid angle #

Answers

Answer 1

Answer: The size of the third angle is 65°.

All interior angles in a triangle must equal to 180°.

So, if 1st and 2nd angle is 115°, then, the 3rd angle would be equal to the difference of 180° and 115°.

3rd angle = 180° - 115° = 65°

Answer 2

Answer: 65
Because a triangles angle all add up to 180
If 2=115
You do- 180-115= 65

Jamil finds that he reads 1/5 of his 115-page book in 1/4 hour

Answers

Answer:

He will read 92 pages in an hour going by the current rate at which he reads

Step-by-step explanation:

The complete question is as follows;

Jamil found that he reads 1/5 of his 115 - page book in 1/4 of an hour. At this rate how many pages does he read in an hour

We proceed as follows;

If he reads 1/5 of 115 in 1/4 hour

1/5 of 115 pages refer to 1/5 * 115 = 23 pages

This means that he reads 23 pages in quarter of an hour

So in an hours the number of pages he will read will be 23 * 4 = 92 pages

What are the roots of 12x = 9 + 5x2?

Answers

minus 12x both sides
0=5x^2-12x+9
use quadratic formula
for 0=ax^2+bx+c
x= $(-b+/- √(b^2-4ac) )/(2a)$

given
5x^2-12x+9
a=5
b=-12
c=9
remember: i=√-1

x= $(-(-12)+/- √((-12)^2-4(5)(9)) )/(2(5))$
x= $(12+/- √(144-180) )/(10)$
x= $(12+/- √(-36) )/(10)$
x= $(12+/- (√(-1))(√(36)) )/(10)$
x= $(12+/- i(√(36)) )/(10)$
x= $(12+/- 6i )/(10)$
x= $(6+/- 3i )/(5)$

the roots are
x= $(6+ 3i )/(5)$ and $(6- 3i )/(5)$

What is 2/3+3k/4=71/12 how do u solve this

Answers

2/3 +3k/4 =71/12

3k/4= 71/12-2/3

3k/4= 71/12-8/12

3k/4=63/12

3k*12=63*4

36k=252

k=252/36

k=7

Hope i helped you!

2/3+3k/4=71/12
= 71/12 - 2/3
=( 71- 8)/12
= 63/12 = 21/4
3k/4 = 21/4
k = 21/4* 4/3
k = 7
