Answer:
Right triangle
Step-by-step explanation:
If the triangle has one angle that measures 50 degrees and another angle that measures 40 degrees, then the last angle must measure 90 degrees because the 3 angles of any triangle add up to 180, so we can set up the following:
180 - (50 + 40) = 90 degrees.
Any triangle that has a 90 degree angle is automatically a right triangle.

<u>Given:</u>
A triangular piece is cut out of a rectangular piece of paper to make the class banner.
<u>To find:</u>
The area of the class banner.
<u>Solution:</u>
The rectangular piece of paper is 14 inches long and 
inches wide.
From the given diagram, the triangle has a base length of the same 8 inches and has a height of 
inches long.
To determine the area of the banner, we subtract the area of the triangle from the area of the rectangle.
The area of a triangle 
The area of the triangle 
square inches.
The area of a rectangle 
The area of the rectangle 
square inches.
The area of the class banner 
square inches.
So the banner has an area of 100 square inches which is the first option.
Answer:
The answer to your question is below
Step-by-step explanation:
1) The triangles are similar by the AA postulate so use proportions to find x.
x/207 = 170/90
solve for x
x = 207(170/90)
x = 207(1.89)
x = 391 ft
2) These triangles are similar so use proportions to solve it
x/138 = (x + 60)/207
207x = 138(x + 60)
207x = 138x + 8280
207x - 138x = 8280
69x = 8280
x = 8280/69
x = 120
Use the slope formula:
8-6
m = ------------ = ???
