Geometry questions....help me someone please

AlekseyPX

Answer:

Triangle 1: x = 80 degrees, acute

Triangle 2: x = 10 degrees, right

Step-by-step explanation:

Triangle 1:

By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:

$60 + 40 +x = 180$

Solve for x:

$100 + x = 180\\x = 80$

So, x = 80 degrees

Because all the angles are less than 90 degrees, this is an acute triangle.

Triangle 2:

By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):

$3x + 60 + 90 = 180$

Solve for x:

$3x + 150 = 180\\3x = 30\\x = 10$

So, x = 10 degrees

Because there is an angle measuring 90 degrees, this is a right triangle.

kap26 [50]

Answer:

The elevation of Lucas Oil Field is of 715 feet.

Step-by-step explanation:

Elevation of Sports Authority Field:

Of 5280 ft.

Compared to Lucas Oil Field:

275ft than seven times the Lucas Oil Field elevation of x.

Equation:

$275 + 7x = 5280$

What is the elevation of Lucas Oil Field?

Solving the above equation:

$7x = 5280 - 275$

$7x = 5005$

$x = \frac{5005}{7}$

$x = 715$

The elevation of Lucas Oil Field is of 715 feet.
