Answer:

Angle A = 19

Step-by-step explanation:

Vertical angles are congruent ( equal to each other )

If angle A and angle B are vertical angles and vertical angles are congruent then angle A = angle B

If angle A = 3x + 13 and angle B = 5x + 9 then 3x + 13 = 5x + 9

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

3x + 13 = 5x + 9

Step 1 subtract 3x from both sides

Outcome: 13 = 2x + 9

Step 2 subtract 9 from both sides

Outcome: 4 = 2x

Step 3 divide both sides by 2

Outcome: x = 2

Now to find Angle A

All we have to do to find the measure of angle a is simply substitute 2 for x in it's given expression ( 3x + 13 )

Substitute 2 for x

Angle A = 3(2) + 13

Multiply

Angle A = 6 + 13

Add

Angle a = 19

What is the value of x?<br><br> A. 142<br> B. 152<br> C. 76<br> D. 71
Nadusha1986 [10]

Answer:

x has a value of 71, making D the correct answer.

Step-by-step explanation:

Because this is an isosceles triangle, we know that the bottom two angles are equal.  We also know that the sum of the angles inside a triangle will always come to 180°.  With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.

x = (180 - 38) / 2\\= 142 / 2\\= 71

So the correct answer is D, 71 degrees.

Answer:

x = 38 degrees.

The angle marked 2x-1  =75 degrees

Step-by-step explanation:

the opposite angles of a parallelogram are equal.

so:

2x -1 = 75

2x = 76

x = 38

Hope this helps

A circle centered at the origin passes through the point (3, 5). What is the area of the circle to the nearest tenth of a square
Mandarinka [93]

Answer:

A = π(34), or approx. 106.8 units²

Step-by-step explanation:

Recall that the formula for the area of a circle is A = πr².

If  (3, 5) is a point on the circle at hand, then the radius (found using the Pythagorean Theorem) is r = √(3² + 5²) = √(9 + 25) = √34.

Then r² = 34, and the area of this circle is

A = π(34), or approx. 106.8 units²
