Answer:
-2x+5
Step-by-step explanation:
slope= -2/1 or -2
y-intercept= 5
Please see the attached picture to see the similar triangle.
The new triangle has triple the side lengths of the first one. This means all side lengths will be triple.
You will use this ratio to find the new side lengths and then use them to find the perimeter and area.
3:4:5 = 9 cm: 12 cm:15 cm on triangleABC
1. The
perimeter is 9cm + 12 cm + 15 cm or
36 cm.
2. The
area is 1/2 x 12 x 9 or
54 square cm.
3. The length of the
hypotenuse is
15 cm.
Answer:
32.98 ft
Step-by-step explanation:
What you have right there is a triangle.
The base of the triangle is given (14 ft)
The angle from the ladder makes while leaning on the house is 67 degrees.
This is a simple trigonometry problem
You want to find the length of the ladder and you don't have the hypotenuse
So you can use the function tan to find it.
tan(Ф) = opposite/adjacent
You are looking for the opposite side length
So you do tan(Ф) * adjacent = opposite
tan(67) * 14 = 32.98 ft
4.5
you divide the fractions then subtract them
