MATHS HEEELLPPP PLEASE THIS IS URGENT

Assuming you need an answer to question #7, here it is.

The sum of all angles inside a polygon depends on the number of sides it has. (n-2) x 180°, where n is the number of sides. Knowing there are 5 sides to the polygon, we can figure out the sum of its interior angles :
(5-2) x 180° = 3x180° = 540°

We know the values of the two right angles on the right side of the shape. They both are of 90° (aka right angle) and add up to 180°. This means that the other angles must make up the rest : 540° (Total) - 180° (right side) = 360° (total of angles A, B and C).

Now we need to make relations between these unknown angles.
1. A=B They were described as having the same size;
2. A=2C A and B were described as being twice as big as C, so we would need two times C to equal A;
3. A+B+C = 360° Which we figured out earlier.

Since B=A we can replace B in the third equation :
A+A+C = 360°
2A+C = 360°
We also know that A=2C :
2(2C)+C=360°
4C+C=360°
5C=360°
We solve for C :
C=72°

Now that we know the value of angle C, we can work our way up towards angles A and B.
A=2C
A=2(72°)
A=144°

B=A
B=144°

We can verify our values to see if it all makes sense.
Is A+B+C=360° still true?
144°+144°+72°=360°
360°=360°

Thus, angles A, B and C are respectively 144°, 144° and 72°.

Anybody know the answer to this

Answer:

1. sin(Z) = 0.6

2. sin(C) = 0.28

3. cos(Z) = 0.8

4. tan(C) = 0.75

5. tan(50°) = 1.1918

6. cos(40°) = 0.7660

7. sin (25°) = 0.4226

8. sin(75°) = 0.9659.

Step-by-step explanation:

The trigonometric ratios are

$cos \ \theta = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}$

$sin \ \theta = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}$

$tan \ \theta = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}$

1. The length of the opposite leg to angle Z = 24

The length of the hypotenuse side = 40

∴ sin(Z) = 24/40 = 0.6

2. The length of the opposite leg to angle C = 14

The length of the hypotenuse side = 50

∴ sin(C) = 14/50 = 0.28

3. The length of the adjacent leg to angle Z = 24

The length of the hypotenuse side = 30

∴ cos(Z) = 24/30 = 0.8

4. The length of the opposite leg to angle C = 27

The length of the adjacent leg = 36

∴ tan(C) = 27/36 = 0.75

5. Using the calculator, and rounding the answers to the nearest 10,000, we have;

tan(50°) = 1.1918

6. Using the calculator, and rounding the answers to the nearest 10,000, we have;

cos(40°) = 0.7660

7. Using the calculator, and rounding the answers to the nearest 10,000, we have;

sin (25°) = 0.4226

8. Using the calculator, and rounding the answers to the nearest 10,000, we have;

sin(75°) = 0.9659.
