To find the hypotenuse, simply use the pythagorean theorem. A^2+B^2=C^2
You know the two legs 7 and 8, so plug it in for A and B
7^2+8^2=C^2
49+64=C^2
113=C^2
C= approximately 10.63
Answer:
x ≈ 2.29 cm
Step-by-step explanation:
From the picture below we are given a right angle triangle and asked to find the value of x. We can use the SOHCAHTOA principle to find the side x.
Base on the angle given the adjacent side of the triangle is x while the hypotenuse is given as 4 cm. Let's find the value of x .
cos 55° = adjacent/hypotenuse
cos 55° = x/4
cross multiply
x = 4 cos 55°
x = 4 × 0.57357643635
x = 2.2943057454
x ≈ 2.29 cm

Answer:
3.9 mi/h
Step-by-step explanation:
If the boy is rowing perpendicular to the current, the two vectors form a right triangle.
AB represents the downstream current, BC is the speed across the river, and AC is the ground speed of the boat
AC^2 = 2.4^2 + 3.1^2 =5.76 + 9.61 = 15.37
AC = sqrt(15.37) = 3.9 mi/h
The boat's speed over the ground is 3.9 mi/h.
