Answer:

350 adult tickets were sold

Step-by-step explanation:

Let "a" represent the number of adult tickets sold. Then the number of student tickets is (a+69) and the total number of tickets sold is ...

a + (a+69) = 769

2a = 700 . . . . . . . . subtract 69

a = 350 . . . . . . . . . divide by 2

Solve the triangle give the measure of y

pishuonlain [190]

Given:

In triangle $BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ$ .

To find:

The value of y.

Solution:

In a right angle triangle,

$\tan \theta=\dfrac{Perpendicular}{Base}$

In triangle BGU,

$\tan B=\dfrac{GU}{BU}$

$\tan 44^\circ=\dfrac{7}{y}$

$0.966=\dfrac{7}{y}$

Isolating y, we get

$y=\dfrac{7}{0.966}$

$y=7.2463$

$y\approx 7.2$

Therefore, the correct option is A.
