Answer:

The correct answer is last option

Step-by-step explanation:

From the figure we can see two right angled triangle.

Points to remember

If two right angled triangles are congruent then their hypotenuse and one leg are congruent

To find the correct options

From the figure we get all the angles of 2 triangles are congruent.

one angle is right angle. But there is no information about the hypotenuse and legs.

So the correct answer is last option

There is not enough information to determine congruency.

Mountain officials want to know the length of a new ski lift from A to C , as shown in the figure below. They measure angle DAC

Ede4ka [16]

We assume that the hill is represented by points ACD and the ski lift is represented by points BCD. From the description above, points CDB would have an angle of 90 degrees. Then, we would have:

sin (32) = CD / 960
CD = 508.72

tan 32 = 508.72 / AD
AD = 814.13

Therefore, the distance would be 814.13 - 508.72 = 305.4 ft.

Find the value of x. Then find the missing angle measures of the polygon

UkoKoshka [18]

Answer:

x=10

5x=50

2x=20

Step-by-step explanation:

110+5x+2x = 180 combine like terms and move the constants to the same side

7x=70

x = 10
