Answer:
13 and 10
Step-by-step explanation:
Answer:
Question 1:
cos a = 0.2195
tan a = 4.445
Question 2:
sin a = 0.8
tan a = 1.333
Step-by-step explanation:
<h3 /><h3>Question 1:</h3>
Given that;
sin a = 40/41
a = sin ⁻¹ (40/41)
a = 77.32°
Now we have to find the value of cos a and tan a:
a = 77.32°
cos 77.32° = 0.2195
tan 77.32° = 4.445
<h3>Question 2:</h3>
Given that;
cos a = 0.6
a = cos ⁻¹ (0.6)
a = 53.13°
Now we have to find the value of cos a and tan a:
a = 53.13°
sin 53.13° = 0.8
tan 53.13° = 1.333
Answer:
The height of the statue is 152 feet
Step-by-step explanation:
<u><em>The complete question is :</em></u>
The total height of the Statue of Liberty and its pedestal is 305 feet. This is 153 more than the height of the statue. Write and solve an equation to find the height h (in feet) of the statue.
Let
h ----> the height of the statue in feet
p ---> the height of the pedestal in feet
we know that
----> equation A
---> equation B
so
substitute equation A in equation B and solve for h
subtract 153 both sides
We know that there are 15 children altogether
We know that the number that voted for B+R is double the number of students voted for G+Y
B+R = 2(G+Y)
Think of two numbers that add up to 15, one number is twice of the other number.
For example, 6 and 12.
12 is double of 6 but 6 + 12 doesn't give 15
So, think again
for example 5 and 10
10 is double of 5 and 5+10 does give 15
So, the number that voted Red and Blue is 10 and the number that voted Yellow and Green is 5
Answer:
The first option: A.) For any numbers a, b, and c, a(b + c) = ab + ac.
Step-by-step explanation:
So anytime that you have a number or letter in front of a set of parenthesis that has numbers within (such as the example problem of: a(b + c)), you need to take the number outside of the parenthesis (a) in this situation) and multiply it to all of the numbers inside the parenthesis, like this:
a(b + c).
Multiply a into b, then multiply a into c, so that the equation looks like this:
ab + ac.
I hope that this helps.
