That is a isosceles triangle, therefore x and the top angle are the same.

There’s 180 degrees in a triangle.

Therefore:

(180 - 38)/2 = x
142/2 = x
71 = x

Answer:

X=71 degrees

Step-by-step explanation:

Because it's an isosceles triangle, the length of two side should be same. Which means two of the angle should also be the same. Therefore, with that information we can get

2x+38=180

Move 38 to the other side

2x=142

Move "2" to another side by divide both side by 2

x=71

Now you get the answer.

Answer:

B) y intercept

Step-by-step explanation:

A) x intercept - Let y = 0 and find the x value

B) y intercept - Let x = 0 and find the y value

C) z intercept Let x and y = 0 and find the z value

D) None of these

(x,y) = (0,-2)

We have x = 0 and we have the y value. This is the y intercept

The top of the Boulder Dam has an angle of elevation of 1.2 radians from a point on the Colorado River. Measuring the angle of e

Nana76 [90]

Answer:

382.925 feets

Step-by-step explanation:

The solution diagram is attached below :

Converting radian measurement to degree :

radian angle * 180/π = degree angle

1.2 * 180/π = 68.755°

0.9 * 180/π = 51.566°

Height of dam is h:

Using trigonometry :

Tan θ = opposite / Adjacent

Tan 68.755° = h / x

h = x Tan 68.755° - - - (1)

Tan 51.566° = h / (155+x)

h = (155+x) tan 51.566° - - - (2)

Equate (1) and (2)

x Tan 68.755 = (155+x) Tan 51.566

x Tan 68.755 = 155tan 51.566 + x tan 51.566

x Tan 68.755 = 195.32311 + x Tan 51.566

x Tan 68.755 - x Tan 51.566 = 195.32311

x(tan 68.755 - tan 51.566) = 195.32311

x * 1.3120110 = 195.32311

1.3120110x = 195.32311

x = 195.32311 / 1.3120110

x = 148.87307

Using :

h = x Tan 68.755

h = 148.87307 * tan(68.755)

h = 382.92539

h = 382.925 feets
