Use the Pythagorus theorem
h^2=p^2+b^2
Here p and b are given
So, h= root under 18^2-7^2
h= 5 root under 11 or 16.58
Answer:
Option (2)
Step-by-step explanation:
In the figure attached,
ΔA'B'C' is a dilation image of ΔABC or both the triangle are similar.
Therefore, by the property of similarity of two similar triangles, corresponding sides these similar triangles will be proportional.
Scale factor =
=
=
=
= 3
Therefore, scale factor is 3 when center of dilation is B.
Option (2) will be the answer.
Answer: a = 18
explanation:
2(a + 10) = 56 -> distribute the 2
2a + 20 = 56 -> subtract 20 from both sides
2a = 56 - 20
2a = 36 -> divide both sides by 2
a = 18
