Problem 1

<h3>Answer: The opposite side is ZY = 18</h3>

Explanation:

This is the leg furthest from angle X. Side XY is the adjacent side while XZ is the hypotenuse.

=======================================

Problem 2

<h3>Answer:  3/4</h3>

Explanation:

The tangent ratio is the opposite over adjacent. With angle X as the reference angle, we will then have ZY = 18 as the opposite side and XY = 24 as the adjacent, so,

tan(angle) = opposite/adjacent

tan(X) = ZY/XY

tan(X) = 18/24

tan(X) = (3*6)/(4*6)

tan(X) = 3/4

sweet-ann [11.9K]

Answer:

62.29%

Step-by-step explanation:

The probability of Aya being offered a coupon on at least one of the six days she visits the website is 100% minus the probability that she is not offered a coupon on any of the six days, which is described by a binomial probability with zero successes in six trials with a probability of succes p = 0.15.

P = 1 - (\frac{6!}{(6-0)!0!}* p^0*(1-p)^{6-0})\\P = 1 - (1* 1*(1-0.15)^{6})\\P=0.6229=62.29\%

The probability that Aya will be offered a coupon on at least one of the days she visits the website is 62.29%.

Can u please find the length of BC round to the nearest tenth
PolarNik [594]

Answer:

Step-by-step explanation:

Using sine rule

SinA/a = SinB/b = SinC/c

A = 84° a = BC, C = 51°, c = 16

Sin84/BC = Sin51/16

Cross multiply

BC Sin51 = 16 × Sin84

BC = 15.91/Sin51

BC = 20.48unit
