Answer:
Step-by-step explanation:
cos R = adj/hyp
R = cos⁻¹(9/10) = 25.8419327... ≈ 25.8°
0 times, x can't go into y
C=100yd, a=60yd, find b
(60yd)^2+b^2=(100yd)^2
3600 yd^2+ b^2 = 10000 yd^2
b^2 = 10000-3600 yd^2
b = sqrt(6400 yd^2)
b=80 yd
Answer: B) 6.5
Step-by-step explanation:
We will use the Pythagorean theorem to solve. The "c" variable is the hypotenuse and the other variables are the legs.
a² + b² = c²
3.6² + b² = 7.4²
12.96 + b² = 54.76
b² = 41.8
b =
b ≈ 6.5
The length of the missing side is about B) 6.5.
