Draw diagarm

we want to know the hyptohuse
use cos

cos(x)=opositeside/hhyptohuse
hypothuse=length of ramp

cos(18°)=26/?
times both sides by ?
?cos(18°)=26
divide both sides by cos(18°)
?=26/(cos(18°))
use your calculator
?=27.338in

the ramp is about 27in

In a triangle , the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 80 mo
Flauer [41]

Answer:

25, 50, and 105.

Step-by-step explanation:

Let the first angle be A, the second angle be B, and the third angle be C.

First, the sum of the three angles in a triangle is 180. Thus:

A+B+C=180

We know that the measure of A is twice the measure of B. Thus:

A=2B

And the measure of C is 80 more than the measure of B. So:

C=80+B

Let's substitute A and C into the original equation:

2B+B+80+B=180

Now, let's solve for the second angle (B). Combine like terms:

4B+80=180

Subtract 80 from both sides:

4B=100

Divide both sides by 4:

B=25

So, the second angle is 25 degrees.

This means that the first angle is 2(25) or 50 degrees.

And the third angle is 80+25 or 105 degrees.

And we're done!

The angles are 25, 50, and 105.

A student claimed that the two equations
Oduvanchick [21]
Solve the first equation for y to compare it to the second equation because the second equation is in terms of y. \frac{y-8}{x-1} =2 \\ 
y-8=2(x-1) \\ 
y-8=2x-2 \\
y=2x+6
Since the first equation simplifies and is the same as the second equation, they are identical equations and their lines when graphed will also be identical.
