Angles In Triangles

Elden [556K]

Answer:

It's a isosceles triangle, i am not saying its clearly implied in the diagram with the red lines.... Which state that both the sides have same length

Hence if on ne side makes 55 with the base therefore the side with same length will make 55 with the base too

Hence its

55+55+x=180

X= 180-55-55

X= 70 degree

Therefore x is 70 degree

Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).

Dvinal [7]

Step-by-step explanation:

Hey there!

The coordinates of a triangle are;

A (1,2)
B (1,-2)
C (-2,-2)
Scale factor = -4 and centre at (0,0)

Now, We have;

P(x,y)----------- P'(kx, ky)

Keep formula;

A(1,2)---------- A'(-4×1 ,-4×2)

= A'(-4, -8)

B(1,-2)------------- B'(-4,8)

C(-2,-2)-------------C'(8,8)

[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

Hope it helps..
