Answer:

2

Step-by-step explanation:

sum of angles in a triangle is 180

(26x - 2) + 70 + 60 = 180

26x -2 = 180 - 70 - 60

26x - 2 = 50

26x = 52

x = 2

hope this helped

Answer:

D) 2

Step-by-step explanation: The interior angles of triangles will ALWAYS add up to 180 degrees. In this case 2 angles are already provided, 70 and 60, so adding those together (130) the remaining angle must be 50 (180-130=50). In 26x-2=50, x=2 is the only possible answer.

A painter leans a 20-ft ladder against a building. The base of the ladder is 12 ft from the building. To the nearest foot, how high on the building does the ladder reach?

Answers

Answer:

The height of the building is 16 ft.

Step-by-step explanation:

It is given that a painter leans a 20-ft ladder against a building. The base of the ladder is 12 ft from the building.

It means the base of the right angled triangle is 12 ft and the hypotenuse is 20 ft.

Let the height of the building be x.

Using Pythagoras theorem,

hypotenuse^2=base^2+perpendicular^2

(200)^2=(12)^2+x^2

x^2=400-144

x^2=256

Taking square root both sides.

x=√(256)

x=16

Therefore the height of the building is 16 ft.
the ladder would reach 16 feet on the building.
Pythagorean theorem helps find this answer.
