One angle of an isosceles triangle measures 138°. Which other angles could be in that isosceles triangle?
BartSMP [9]

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

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 = \frac{7}{4}

Therefore, x is equal to \frac{7}{4}.

<em>Hope this helps! :)</em>

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.
