Find all solutions for a triangle with a = 14, b= 12, and B = 90°.
ziro4ka [17]

Answer:

No solution.

Step-by-step explanation:

Given

a = 14; b= 12; B = 90^\circ

Required

Find all possible solutions

If B = 90^\circ, then the triangle is right-angled and the hypotenuse is at b

Given that a = 14; b= 12;

This implies that a > b

In a right-angled triangle, the hypotenuse (side b) is the longest.

Since this is not true for the given sides, then the triangle has no solution.

What is the length of AC?
sladkih [1.3K]
When the question says that triangle ABC ~ triangle DEF, that means the triangles are similar. This means that their proportions are the same.
In triangle ABC, side length AB is the equivalent of side length DE in triangle DEF.

Since the proportions must be the same, we can take the known side from triangle ABC, find the equivalent of it on triangle DEF, and find the proportions.
We already found that side length AB ~ side length DE.
Now we can divide the lengths to find the proportions.
28 / 8 = 3.5
This means that each side on triangle ABC will be 3.5 times greater than the equivalent side on triangle DEF.

The length of AC in triangle ABC is 3.5 times the length of DF in triangle DEF.
Side length DF is 10.
Multiply 3.5 by 10 to get the length of AC.
3.5 • 10 = 35
So the length of AC is 35 units.

Answer:
Side length AC in triangle ABC is 35 units.

Hope this helps!

Kevin and Michelle traveled together by car and shared the driving. Kevin drove for 3.25 hours, then Michelle drove for 1.5 hour
jek_recluse [69]

Using the relation of velocity, distance and time, it is found that 35 represents Michelle's velocity.

-----------------------------

Velocity is <u>distance divided by time</u>, then:

v = \frac{d}{t}

Kevin drove for 3.25 hours, thus t_1 = 3.25. The distance drove by Kevin is:

d_1 = v_1t_1

d_1 = 3.25v_1

Michelle drove for 1.5 hours, thus t_2 = 1.5. The distance drove by Michelle is:

d_2 = v_2t_2

d_2 = 1.5v_2

The total distance is:

d = d_1 + d_2

d = 3.25v_1 + 1.5v_2

Comparing to the expression:

3.25v_1 + 1.5v_2 = 3.25(42) + 1.5(35)

We get that 42 is Kevin's speed and 35 is Michelle's speed.
