Answer:
perimeter: 42 in.
Step-by-step explanation:
separate the triangle, in the smallest triangle find the missing length of that side (hypotenuse: 13, short leg: 5, long leg: ?), which is (long leg) 12 in. (a^2+b^2=c^2 then 5^2+b^2=13^2) do the same process with the other half of the triangle. and you have your answer. hope this helped :)
Consider an angle M with measure m≠90°, in a right triangle.
Let
OPP denote the length of the side opposite to M,
ADJ denote the length of the side adjacent to M, and
HYP denote the hypotenuse.
then:
Sin(M) = OPP/HYP
Cos(M)= ADJ/HYPP
Tan(M)=OPP/ADJ
Back to our problem,
using the Pythagorean we can find the length of AB:






Answer: 1, 3, 4
6,600,000,000 in scientific notation is 6.6 × 10^9
Answer:
41.5675675676km/hour or 41.57km/hour
Step-by-step explanation:
158÷3.7=41.5675675676 or 41.57
Scale of the model = 3.5 / 10.5 = 1/3
so the length of the model = 1/3 * 12 = 5 feet
Area of the scale model = 4 * 3.5 = 14 sq ft
