Answer:

80°

Step-by-step explanation:

<u>The angles of a triangle must add up to 180°.</u>

40° + 60° + missing angle = 180°

100° + missing angle = 180°

<em>subtract 100° from both sides</em>

missing angle = 80°

Set of integers x such that x - 5 ​
My name is Ann [436]

The set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The question is incomplete.

The complete question is:

Set of integers x such that x - 5 is less than 25​.

We have an inequality:

x - 5 < 25

Adding 5 both sides:

x - 5 + 5 < 25 + 5

x < 30

x ∈ (-∞, 30) where x is an integer.

Thus, the set of integers that satisfy the inequality is x ∈ (-∞, 30) where x is an integer.

Use the information and diagram to answer the following question.
nevsk [136]

Answer:

910 ft

Step-by-step explanation:

This question sets up the equation tan20°=x/2,500. Solve for X by multiplying 2,500 on both sides giving you x = 2,500tan20°. Finally, plug that in a calculator and you get 909.92. Round it to the nearest foot and you get 910
