If tan a = 9/40<br>use trigonometric identities to find the values of sin a and cos a.​
Sindrei [870]

Answer:

see explanation

Step-by-step explanation:

Given

tan a = \frac{9}{40} = \frac{opposite}{adjacent}

We require the hypotenuse h

Using Pythagoras' identity

h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )

h = \sqrt{1681} = 41 , thus

sin a = \frac{opposite}{hypotenuse} = \frac{9}{41}

cos a = \frac{adjacent}{hypotenuse} = \frac{40}{41}

Louise's family traveled 3 10 of the distance to her grandmother's house on Saturday. They traveled 4 7 of the remaining distanc
Ludmilka [50]

Answer:

4/10

Step-by-step explanation:

Louise's family traveled 3/10 of the distance to her grandmother's house on Saturday.

Let us represent total distance = 1

The remaining distance left is calculated as:

1 - 3/10

Lowest common denominator = 10

= 10 - 3/10 = 7/10

They traveled 4/7 of the remaining distance on Sunday.

This is calculated as:

= 4/7 × 7/10

= 4/10

What fraction of the total distance to her grandmother's house was traveled on Sunday?
