Question 7: Option 1: x = 33.5°

Question 8: Option 3: x = 14.0°

Step-by-step explanation:

Question 7:

In the given figure, the value of perpendicular and hypotenuse is given, so we have to use any trigonometric ratio to find the value of angle as the given triangle is a right-angled triangle

So,

Perpendicular = P = 32

Hypotenuse = H = 58

So,

$sin\ x = \frac{P}{H}\\sin\ x = \frac{32}{58}\\sin\ x = 0.5517\\x = sin^{-1} ( 0.5517)\\x =33.48$

Rounding off to nearest tenth

x = 33.5°

Question 8:

In the given figure, the value of Base and Perpendicular is given, we will use tangent trigonometric ratio to find the value of x

So,

Perpendicular = P = 5

Base = B = 20

So,

$tan\ x = \frac{P}{B}\\tan\ x = \frac{5}{20}\\tan\ x = 0.25\\x = tan^{-1} (0.25)\\x = 14.036$

Rounding off to nearest tenth

x = 14.0°

Answer:

2 5/12

Step-by-step explanation:

8 5/6 + 2 3/4 = 8 10/12 + 2 9/12 = 10 19/12 = 10 + 1 7/12 = 11 7/12

13 12/12 - 11 7/12 = 2 5/12

During a 60 minute television program, 25% of the time is used for commercials and 5% of the time is used for the opening and cl

aksik [14]

Answer:

42 minutes

Explanation:

The total amount of anything expressed in percentage is 100%.

The reason for this is that per cent means per hundred.

So, 100% is

100

, which is a whole.

Moving to the question, a total of 25% + 5% = 30% of the time is used up by commercials and credits.

The time left for the program is 100% - 30% = 70%.

This is 70% of 60 minutes or

100
