Answer:

13.5

18.1

72.2

12.8

6,2

66.1

49.1

14

31.8

Step-by-step explanation:

In solving this question, remember the annotation SOHCAHTOA

1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value

Cos 26 = Adjacent / hypotenuse

cos 26 = x / 15

x / 15 =0.8988

x = 15 x 0.8988 = 13.5

2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value

Sin = opposite / hypotenuse

sin 49 = x / 24

0.7547 = x / 24

x = 0.7547 x 24

x = 18.1

3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value

Tan = opposite / adjacent

tan 14 = 18 /x

18 / 0.2493 = 72.2

4.  We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value

cos 67 = opposite / hypotenuse

0.3907 = 5/x

x =5/  0.3907 = 12.8

to determine the missing angle

7. tan^-1 = opposite / adjacent

8. cos^-1 = adjacent / hypotenuse

9 = sin^-1 = opposite / hyotensue

The radius of a circle is 7m , find its area in terms of π
dangina [55]

Answer:

49π

Step-by-step explanation:

A = π r^{2}

A = π 7^{2}

A = 49π

For the one you put in the comment...

The radius of a circle is 19cm find its area in terms of π

A = π r^{2}

A = π 19^{2}

A = 361π

For the other one you put in the comment

The radius of a circle is 4 cm find its area in terms of π

A = π r^{2}

A = π 4^{2}

A = 16π

For the other one you put in the comment

The radius of a circle is 20 cm find its area in terms of π

A = π r^{2}

A = π 20^{2}

A = 400π

Hope this helped!
