Answer:
None
Step-by-step explanation:
The sum of the angles of every triangle must add up to 360 degrees. 80+80+20=200, thus no triangle can be constructed with these angles.
1.
7x - y = 5
Isolate y
Add y
7x = y + 5
Subtract
y = 7x - 5 2.
5x - 3y = 0
Isolate y
Add y
5x = 3y
Divide
y = 1.66x 3. v=iwh
Isolate w
Divide h
v/h = iw
Divide I
v/hi = w
0.6=6/10 so after simplifying you get 3/5, hope it helps !!
Answer: 20:3
Step-by-step explanation:
=) 2 cm = 20 mm
therefore, 20:3

How do you find the area of a triangle
To find the area of a triangle, you need to know the formula of the triangle to work it out. The following is the formula of the triangle:
H - height
B- Base
You need to multiply the base and height and divide it by 2.
Lets solve a question!
Find the area of a triangle with a base of 32mm and a height

of 35mm
Area =

=

=

=

Hope I helped (:
Have a great day!
