Perimeter of the new triangle is 1505 ft
Step-by-step explanation:
- Step 1: Given the perimeter of the right triangle = 215 ft. Find new perimeter.
Perimeter of the triangle = sum of the sides = a + b + c = 215
Each side is multiplied by 7, so new sides are 7a, 7b, 7c
⇒ New perimeter = 7a + 7b + 7c = 7(a + b + c) = 7 × 215 = 1505 ft
-8,-3 if i read that correctly, that should be the answer.
Answer: 23
Step-by-step explanation: 18+5=23
23-5=18
R=23
SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.
Sin = Opposite/Hypotenuse
In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).
sin(30°) = height/(3000 m)
Multiplying by 3000 m, we get
height = (3000 m)*sin(30°) = 1500 m
The height of the plane at that instant is ...
1500 m
