Answer:

height is 5 units

Step-by-step explanation:

We are required to determine the height of a triangle that has an area of 30 square units and a base measuring 12 units.

The formula for the area of a triangle is given as;

$Area=\frac{1}{2}*base*height$

We plug in the given values and solve for the height;

$30=\frac{1}{2}*12*height\\\\30=6*height\\height=5$

What is... X/2 - 13 = 1

kow [346]

X ÷ 2 - 13 = 1
Write the division as a fraction
$\frac{1}{2}x - 13 = 1$
Multiple both sides of the equation by 2
$2 \times \frac{1}{2}x \times - 2 \times 13 = 12$
Reduce the number with greatest common divisor 2
$x - 2 \times 3 = 2$
Multiply the numbers
$- 2 \times 13$
Then u will have
$x - 26 = 2$
Move constant to the right by adding its opposite sides
$x - 26 + 26 = 2 + 26$
Eliminate the opposites
$- 26 + 26$
Then you have
$x = 2 + 26$
Add the numbers
$x = 28$

Use the diagram to find the measure of angle KHL.

bija089 [108]

Answer:

m∠KHL = 43°

Step-by-step explanation:

From the picture attached,

m∠KHL ≅ m∠GHL [Given in the picture]

Now substituting the values of the angles,

(3x + 1) = (5x - 27)

1 + 27 = 5x - 3x

28 = 2x

14 = x

m∠KHL = (3x + 1)° = (3 × 14) + 1

= 42 + 1

= 43°

Therefore, measure of ∠KHL = 43°

A grid shows the positions of a subway stop and your house. The subway stop is located at (7, -6) and your house is located at (

Yuri [45]

So the distance between subway stop and house is 19 units

Step-by-step explanation:

The distance formula will be used to calculate the distance between home and subway.

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Here (x1,y1) are the coordinates of first point

and

(x2,y2) are the coordinates of second point

Given

(x1,y1) = (7, -6)

(x2,y2) = (-9,5)

Putting the values in the formula

$d=\sqrt{(-9-7)^2+(5-(-6))^2} \\=\sqrt{(-16)^2+(5+6)^2} \\=\sqrt{256+(11)^2}\\=\sqrt{256+121}\\=\sqrt{377}\\=19.41\ units$

Rounding off to nearest unit gives us 19.

So the distance between subway stop and house is 19 units
