Answer:
120
Step-by-step explanation:
all angles of a triangle add up to 180. 180-15-45= 120.
:D
brainliest pls
Given :
Measure of an angle = 15°
Measure of the second angle = 45°
Let the measure of the third angle be x.
We know that :
▪︎Sum of all angles of a triangle = 180°[angle sum property]
Which means :
[tex] =\tt 15 + 45 + x = 180[/tex]
[tex] =\tt 60 + x = 180[/tex]
[tex] =\tt x = 180 - 60[/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 120°[/tex]
Thus, the measure of the third angle = 120°
Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.
Therefore, the correct option is (C) 120

Answer:
(-3, -5)
Step-by-step explanation:
We will multiply (6a -2b = -8) by -3, and (a - 3b = 12) by 2
Thus,
-18a + 6b = 24
2a - 6b = 24
=
-16a = 48
a= -3
Then we'll substitute,
-18(-3) + 6b = 24
54 + 6b = 24
6b = -30
b = -5

Given that Patrick is x years old and his brother is 9 years older than he is. Then;
His brother's age will be

y = x + 9
Since y is the subject, y has been expressed in terms of x. Where y is the age of Patrick's brother and x is Patrick's age.
Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much of the pot is left over? PLS HELP I HATE MATH
Answers
Answer:
3/4 of the pot left.
Step-by-step explanation:
If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.
Answer:
3/4 of the pot is left over
Step-by-step explanation:

A rectangle is a parallelogram, which means that opposite sides are parallel. This means that both of the short sides equal 12. 12 plus 12 is 24, so substract 24 from 36 to get 12. This means that the sum of the long sides are 12; half of 12 is 6 so that is the length of one of the sides. This means that you can set the equation 4x - 6 equal to 6. Add 6 to both sides to get 4x = 12, then divide both sides by 4 to get x = 3. I think your equation should be 4x - 6 = 6, and x equals 3.
Sorry if I'm wrong, if I'm right then that picture of the rectangle is really misleading.
