Answer:
9.2
Step-by-step explanation:
The given triangle is a right angled triangle. To solve for any of the side length of such triangle, apply the trigonometry ratio formula which can easily be remembered as SOHCAHTOA.
SOH is Sin θ = opposite/hypothenuse,
CAH is Cos θ = Adjacent/hypotenuse
TOA is Tan θ = Opposite/adjacent
Thus, in the right triangle given, we have:
θ = 38°
Opposite side to the given angle = x
Hypotenuse = 15
We're going to use, sin θ = opposite/hypotenuse
Sin(38) = x/15
Multiply both sides by 15 to solve for x
15*sin(38) = x
15*0.616 = x
9.24 = x
<em>x ≈ 9.2 (to nearest tenth)</em>
Answer:
24
Step-by-step explanation:
definition of coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y)
100 - 55
10 - x
= 5.5
if 100% is 55, what is 10%? multiply 10 by 55 and then divide it by 100
Answer: Option A
Center: (3,-2)
Radius: 6
Rewrite in standard form to find the center (h,k) and radius r.
Experimental probability is the chance an event has to occur. It is derived from the number of times an event occurs to the total number of trials. You can use the following formula to calculate it. P = (o/t) * 100%, where o is the number of times the event occurred, and t is the total amount of trials ran. In this case, P = (66/101) * 100, which evaluates to P = 65.3% (after rounding)
Answer: 65.3%
