Step-by-step explanation:
3/6=k/7
cross multiply then
6k=21
divide by the coefficient of k
k=3.5
Answer:
1) 114
2) 159
Step-by-step explanation:
2+8+5+9+90 = 114
3+45+111 = 159
Hope this helps.
The rule for dilation (scale factor k) about the origin is given by:
(x,y)->(kx,ky)
For the point P(4,10)
the image is therefore
P(4,10)->P'(4k,10k) [ since k is not numerically given ]
When k is known numerically, substitute k into P' to find the numerical coordinates.
Answer:
Triangle 1: 90°, 20°
Triangle 2: 20°, 90°
Step-by-step explanation:
According to AA or Angle-Angle Similarity, any two triangles with two of the same angle measurements are similar. Only Triangle 1: 90°, 20° and Triangle 2: 20°, 90° have the same two angle measurements.
