Answer:
8.5 cm
Step-by-step explanation:
Angles of the triangle:
Right triangle as it has 90° angle
Sides are a, b and 19 cm
- sin 30°= a/19 ⇒ a= 19 sin 30°= 19*0.5= 8.5 cm = shortest side
- sin 60°= b/19 ⇒ b= 19 sin 60°= 19*0.866= 16.45 cm
Answer: Option C: 44
Step-by-step explanation:
so, here we have the equation:
H(a,b) = 2a + 4b
"evaluate" means change the values of the variables for specific values, here we must replace the "a" for 10, and the "b" for a 6.
So we have:
H(10, 6) = 2*10 + 4*6 = 20 + 24 = 44
