Answer:

x=4.8

This here you use Pythagorean Theorem.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is c. And the two legs are a and b.

So it'd be 11^2+x^2=12^2

121+x^2=144

Subtract 121 from both sides.

x^2=23

Then take the √ of x^2 and 23

So √x^2=√23

x=4.8

Hope this helps

Identify the angles that each have a measure of 124º.
Natali5045456 [20]

Answer:

Angle 1, angle 3 and angle 7 will be the equal angles.

Step-by-step explanation:

In the figure attached,

Two lines are parallel and a transversal line is intersecting these parallel lines.

Congruent angles to the angle measuring 124° will be,

m(∠7) = 124° [Vertical angles]

m(∠1) = 124° [Corresponding angles]

m(∠3) = 124° [Alternate interior angles]

Therefore, ∠1, ∠7 and ∠3 will measure the same as 124°.

Select the correct answer. What is the range of this data? (3,3, 0, 8, 7, 10, 2, 6, 12, 0}
Natasha2012 [34]

Answer:

D: 12

Step-by-step explanation:

The range is the difference between the largest value in the date minus the smallest value in the data.

In this set of numbers given, the largest value is 12 and the smallest value is 0

so: 12-0 = 12

The range of this data is 12
