Let the base angle be x. If the obtuse angle is two and a half times the base angle, it will be 2.5x. In a triangle, all three angles will add up to 180. The third angle, the other base angle will be equal to x. So the equation will be:

x + x + 2.5x = 180
2x + 2.5x = 180
4.5x = 180
x = 40

If x = 40, then 2.5x = 100

the point B(-3, -2) is translated 4 units left. what are the coordinates of the resulting point, B’?
ololo11 [35]

Answer:

B'(-7 , -2)

Step-by-step explanation:

First we must understand the coordinate-axis, when we want to move a point to the left or right we do it on the x-axis. to move up or down is on the y axis.

now if we move to the left we go to the negative and to the right the positive

as we are going to move to the left we have to subtract the value that he gave us (4) only to the part of x

B(-3 , -2)

-3 - 4 = -7

B'( -7 , -2)
