Mathematics
1 answer:
Burka [1]3 years ago
7 0

Answer:

x=20

Step-by-step explanation:

3x - 10 + 5x + 30 = 180

8x + 20 = 180

8x = 160

x = 160/8

x = 20

check:

3(20) - 10 + 5(20) + 30 = 180

60 - 10 + 100 + 30 = 180

50 + 100 + 30 = 180

150 + 30 = 180

180 = 180 ✓

Enlarge the triangle by scale fador 3 using the blue det<br> as the centre of enlargement
DochEvi [55]

Answer:

Step-by-step explanation:

Let the blue point is located at the origin.

Therefore, coordinates of the vertices of the given triangle ABC will be,

A(2, 1), B(2, -1) and C(3, -1)

Rule for the dilation of a point (x, y) by a scale factor 'k' will be,

(x, y) → (kx, ky)

By applying this rule, coordinates of the image points of the vertices will be,

A(2, 1) → A'(2k, k)

          → A'(6, 3) for (k = 3)

B(2, -1) → B'(6, -3)

C(3, -1) →C'(9, -3)
