Three straight lines are shown in the diagram.

Mathematics
1 answer:
ANTONII [103]2 years ago
8 0

The sizes of angles a, b and c of the diagram not drawn to scale are 50°, 100°, and 30° respectively.

The angles a, b and c are angles in a triangle.

Therefore, the sum of a , b and c should be equals to 180 degrees.

<h3>Angle a</h3>

let's find angle a using the rule as follow:

  • sum of angle at a point is 360 degrees

Therefore,

a = 360 - 310 = 50°

<h3>Angle b</h3>

let's find angle b using the rule as follow:

  • Angle on a straight line is equals to 180 degrees.

Therefore,

b = 180 - 80 = 100°

<h3>Angle c</h3>

let's find angle c using the rule as follow:

  • Sum of angle in a triangle is 180 degrees

Therefore,

c = 180 - 50 - 100 = 30°

Simplify the expression 1-cos^2(t) / cos^2(t)
OLEGan [10]

Answer: \tan^2 t

Step-by-step explanation:

\sin^{2} t+\cos^2 t=1 \implies 1-\cos^2 t=\sin^2 t\\\\\implies \frac{1-\cos^{2}t}{\cos ^2 t}=\frac{\sin ^2 t}{\cos^2 t}=\tan^2 t

Nuetrik [128]

Answer:

$19.6

Step-by-step explanation:

He bought 6 video games and 1 dvd

We know that each video game costs $2.7 and each dvd costs 3.4

To get the sum = v x 6 + d x 1

= 2.7 x 6 + 3.4 x 1

= 16.2 + 3.4

= $19.6

Who's is the solution set of the compound inequality 3.5x-10&gt;-3 and 8x-9&lt;39
velikii [3]
3.5x-10>-3  add 10 to both sides

3.5x>7  divide both sides by 3.5

x>2

... now for the other inequality:

8x-9<39  add 9 to both sides

8x<48  divide both sides by 3

x<6

So we have x>2 and x<6, so the compound inequality is:

2<x<6  and this means that the solution set is:

x=(2, 6)
