Answer:
280 m
Step-by-step explanation:
a² + b² = c²
450² + b² = 530²
202,500 + b² = 280,900
280,900 - 202,500 = 78,400
√78,400 = 280
Answer:
Ratio of area of triangles MNP and ABC is 1.05
Step-by-step explanation:
There are 2 triangles ABC and MNP.
We are given that ,m∠A = m∠M.
AB = 16 and AC = 10.
MN = 7 and MP = 24.
Area of a triangle ∝ Product of any two sides.
So area of triangle ABC ∝ 16
Area of triangle ABC = 160 ,
where k is a constant.
So area of triangle MNP ∝ 7
Area of triangle MNP = 168
So ratio of area of triangles =
=
= 1.05
