Answer:
34.78 feet
Step-by-step explanation:
1) using the cosine function, I did cos(43)=x/51
This is because cosine is equal to adjacent over hypotnuse
Once I found x, I used the pythagorean theorem to get 34.78 feet
Question:
An isosceles triangle has a base of 9.6 units long. If the congruent side lengths have measures to the first decimal place, what is the possible length of the sides? 9.7, 4.9, or 4.7
Answer:
4.9 is the shortest possible length of the sides.
Step-by-step explanation:
Given:
The base of the triangle base = 9.2 units
To Find:
The shortest possible length of the sides = ?
Solution:
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
So According to the theorem




In the given option 4.9 is the shortest length greater than 4.8 that can be possible.
Answer:
The area of the triangle with the given measurements is 200 in²
Step-by-step explanation:
For this problem, we will need to know the formula for finding the area of a triangle.
<em>A = 1/2(bh)</em>
Now, let's plug in these numbers so we can find the area.
A = 1/2(bh)
A = 1/2(16*25)
A = 1/2(400)
A = 200 in.²
Hello,
A fraction is not defined if its denominator is null.
3x²-75=0
==>3(x²-25)=0
==>(x+5)(x-5)=0
==>x=-5 or x=5
Answer:
12 mph
Step-by-step explanation:
First 30 miles while cycling at 15 mph. This means he spent 2 hours here.
Thus the 4 hours on the last 48 miles.
Average speed = distance / time
Average speed = 48 miles / 4 hours
Average speed = 12 mph
Therefore Regan's average speed is 12 mph for the last 48 miles.
