First we need to find all the interior angles. So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180.
2x + x + 60 = 180
Now lets start to solve. First let's subtract the 60 from both sides.
2x + x = 120
Now we need to add the x's together.
3x = 120
Now we must divide the 120 by 3 to get x by itself.
x = 40
Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so <EHG would be equal to 80.
ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do!
Step-by-step explanation:
Firstly let's calculate the unknown angles in triangle ABC
2x + x + 60° = 180° { being sum of angles of triangle }
3x = 180° - 60°
3x = 120°
x = 120° / 3
x = 40°
2x = 2 * 40° = 80°
Now since it is said that triangle ABC and triangle EHG are similar so
< EHG = < ABC = 2x = 80°
Hope it will help :)

answer is 3 11/12
Step-by-step explanation:
1 4/6 =10/6
2 1/4=9/4
when adding fractions that are do not share a common denominatour you have to find a common multiple
which in this case is 12
so 9/4 timesed the top and the bottom by 3 gives you 27/12
and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

Answer:

-1 + 14x = 12x + 17
Answer:
x = 9
Step-by-step explanation:
-1 + 14x = 12x + 17
Rearrange terms.
14x - 1 = 12x + 17
Add 1 to both sides of the equation.
14x - 1 + 1 = 12x + 17 + 1
Simplify.
14x = 12x + 17 + 1
14x = + 12x + 18
Subtract 12x from both sides of the equation.
14x - 12x = + 12x - 12x + 18
Simplify.
2x = + 12x - 12x + 18
2x = 18
18 ÷ 2 = 9
x = 9

Nhich number line represents the solutions to |x + 4| = 2?
Answers
Answer:
I'm guess that the parentheses looking sign means absolute value so the answer should be the first choice. (-6, and -2)
Step-by-step explanation:
-6 plus 4 = -2 but since we are doing absolute value then the absolute value of -2 is 2.
-2 plus 4 = 2 So, this is also correct because the answer is 2.
Hope this helps! :)
The solution is represented by the first number line, which has the solutions x=-6 and x=-2.
What is number line?A number line is a pictorial representation of numbers on a straight line. In elementary mathematics, a number line is a picture of a graduated straight line that serves as visual representation of the real numbers. Every point of a number line is assumed to correspond to a real number, and every real number to a point.
here, we have,
We have an absolute value function for the equation.
This means that we should have two different solution in the real number line.
As the equation is
|x + 4| = 2
when we clear out the absolute value, we will have two possible solutions:
x + 4 = 2
and
-(x + 4) = 2
now we clear x from both equations
x + 4 = 2 ⇒ x = -2
-(x + 4) = 2 ⇒ x = -6
Then, we have that x=-2 and x=-4 are the solutions for the equation, and therefore the number line that represents the solution is the first one, where the points -6 and -2 are highlighted.
