Answer: 25.0

Step-by-step explanation:

In the given figure ST is a diameter of the Circle.

The central angle subtended by a diameter in a circle is 180°.

Then, According to the given figure , we have

$(2x+8)^{\circ}+(3x-14)^{\circ}+(3x-14)^{\circ}=180^{\circ}\\\\\Rightarrow\ 2x+8+3x-14+3x-14=180\\\\\Rightarrow\ 8x-20=180\\\\\Rightarrow\ 8x=180+20\\\\\Rightarrow\ 8x=200\\\\\Rightarrow\ x=\dfrac{200}{8}\\\\\Rightarrow\ x==25$

Hence, the value of x is 25.0.

Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest poss

julia-pushkina [17]

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

$c^2 > a^2 +b^2$

$c^2 > (9)^2 +(14)^2$

$c^2 > 81 +196$

$c^2 > 277$

c > 16.64

Therefore the smallest possible whole number is 17 inches.

Finding Distance on the Coordinate Plane

Vocabulary Tip

To help review terms shown here, see “Coordinate plane” in the Glossary.

You can think of a point as a dot, and a line as a series of points. In coordinate geometry you describe a point by an ordered pair (x, y), called the coordinates of the point.

The coordinates of point T

are (5, 2).

The coordinates

of point R are (4, 1).

You can use the Ruler Postulate to find the distance between two points if the points are on a horizontal line or a vertical line. To find the distance between two points that are not on a horizontal or vertical line, you can use the Distance Formula.

Key Concepts

The distance d between two points A(x1, y1) and B(x2, y2) is

d= (x 2x) 1(y 2y). #212212

Please help me with geometry.

disa [49]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

Parallel lines have the same slope.

Therefore if k: y = 6x + 7 → m = 6, and l: y = mx +b,

then l is parallel to k if m = 6.

We have the equation: y = 6x + b.

The line l passes through (0, 9). Therefore b = 9.

Finally we have:

y = 6x + 9
