Answer:
105 degrees
Step-by-step explanation:
The measure of the exterior angle of a triangle is equal to the sum of the measures of the other angles of the triangle.
Given that, we know the missing angle is 25 + 80 = 105.
Answer:
the length is 12 and the width is 9.
Step-by-step explanation:
The first step is always to assign letters to the variables. We can call length L and width W.
Since all units are in cm, unit conversion is unnecessary.
Next, set up some equations. L=2W-6 because of the first sentence of the problem. Length times width equals area, so L*W=108.
Now that there are two equations and two variables, the next step is to solve the system. I'm going to solve it by plugging in the right side of the first equation in for L in the second equation. This gives me (2W-6)*W=108. Distributing the W gives me 2W^2-6W=108, or W^2-3W-54=0. Using the quadratic formula, I get that W=9. Using the first equation, L=2*9-6=12. So the length is 12 and the width is 9.
-400-(-700)
-140+700
= 300
I hope that's help ! If you have question(s) please let me know
A square with a perimeter of 48 inches would have 12 in sides, while a triangle of the same perimeter would have 16 in sides. The ratio would be 16/12 which simplified to 4/3.
