Answer:
2 21 degree angles
Step-by-step explanation:
An isosoles triangle has two congruent angles and every triangle's sum of interior angles equals 180 degrees. 138*2>180, so the 138 degree angle cannot be congruent to any of the other angles. Therefore:
180=138+2x
42=2x
21 degrees=x
Answer:
23 decries up wards then move it down twice :)
Step-by-step explanation:
If their perimeters are equal, we can add up all the side lengths of each triangle, and set the perimeters equal to each other to find the value of x that satisfies the equation:
x - 2 + x + 3x + 1 = 2x - 5 + x + 4 + 6x - 7
Combine like terms:
5x - 1 = 9x - 8
And finally, solve for x:
7 = 4x
x = 
Therefore, x is equal to .
<em>Hope this helps! :)</em>
Answer:
-8
Step-by-step explanation:
you have to make them equivalent so and the one thing missing from the other side of the equation
Answer:
The y-intercept represents the price of the computer last Monday.
Step-by-step explanation:
The y-intercept is the point on a graph where x equals zero. Also, the y-intercept is the output value in an equation when x equals zero.
In this situation, x represents the number of days since last Monday. So, when x equals zero, no time has passed.
Therefore, the y-intercept represents the price of the computer last Monday.
