Triangle BCD~ Triangle SQR. What Is Angle S?
ad-work [718]
Answer: The measure of angle S is 62 degrees.

There are 2 ways to find the answer. 

First, the triangles are similar. That means that all the angles will be the same. Since, angle S is corresponding to angle B, it will have the same measure.

Second, there are always 180 degrees in a triangle. Therefore, we can write and solve the following equation about the angles in triangle SQR.

x + 41 + 77 = 180
x + 118 = 180 
x = 62

Calculate the total surface area of 20cm long 10 cm wide and 5 cm high box
stiv31 [10]

Answer:

Given

Edge of a cube = 10cm

Length, l = 12.5 cm

Breadth, b = 10cm

Height, h = 8 cm

Find out

We have to find

i) Which box has the greater lateral surface area and by how much?

ii) Which box has the smaller total surface area and by how much?

Solution

(i)

Lateral surface area of a cube = 4 * (edge)2

= 4 * 102 cm2

= 400 cm2

Lateral surface area of a cuboid = 2 (lh + bh)

= 2 (12.5 * 8 + 10 * 8) cm2

= 2 (100 + 80) cm2

= 360 cm2

So, the lateral surface area of the cubical box is greater than cuboidal box by (400 cm2 – 360 cm2) which is 40 cm2.

(ii)

Total surface area of a cube = 6 * (edge)2

= 6 * 102 cm2

= 600 cm2

Total surface area of cuboid = 2 (lb + bh + lh)

= 2 (12.5 * 10 + 10 * 8 + 12.5 * 8) cm2

= 2 (125 + 80 + 100) cm2

= 610 cm2

Therefore, the total surface area of the cuboidal box is greater than the cubical box by (610 cm2 – 600 cm2) which is 10 cm2.

What does n for n mean?​
andrey2020 [161]

The problem is asking you to solve the equation

<em>y</em> = 12<em>x</em> + <em>n</em>

for the variable <em>n</em>. To do this, subtract 12<em>x</em> from both sides:

<em>y</em> - 12<em>x</em> = (12<em>x</em> + <em>n</em>) - 12<em>x</em>

<em>y</em> - 12<em>x</em> = <em>n</em>

Which shows a graph of a linear equation in standard form Ax + By = C, where A = 0, B is positive, and C is negative? A coordina
il63 [147K]

Answer:

A coordinate plane with a horizontal line passing through (negative 4, negative 3), (0, negative 3) and (4, negative 3).

Step-by-step explanation:

Ax + By = C, where A = 0, B is positive, and C is negative

By= C or y= C/B which is negative

Since A is zero and C is negative, the line is parallel to x- axis and has negative value for y, so it is a horizontal line below zero

---------------

A coordinate plane with a vertical line passing through (1, negative 4), (1, 0) and (1, 4).

no, the line is horizontal

A coordinate plane with a vertical line passing through (negative 2, negative 4), (negative 2, 0) and (negative 2, 4).

no, the line is horizontal

A coordinate plane with a horizontal line passing through (negative 4, 4), (0, 4) and (negative 4, 4).

no, the y-values should be negative

A coordinate plane with a horizontal line passing through (negative 4, negative 3), (0, negative 3) and (4, negative 3).

yes, this is horizontal line below zero
