You can find the exterior angle by adding the 'two opposite isolated angles' together to find the exterior angle.
hope this helps
Answer:
The area of a right-angle triangle is; Area = a x b / 2
Step-by-step explanation:
A right-angle triangle just like conventional triangle, has three sides.
The sides are labelled a, b and c. With a as the height of the triangle and b as the base and c as the slope or the hypotenuse.
The area of a triangle is: (base/2) x height
This is similar to the area of the right-angle triangle which is also half of the base multiplied by the height of the triangle, that is,
Area = ab / 2
First choose 1 equation and set it equal to 180 because supplementary angles equal up to 180 degrees.
12q - 9 =180
Now solve for q.
12q - 9 +9 = 180 + 9
12q = 189
12q/12 = 18912
q = 15.75
now subtract 15.75 from 180
180.00 - 15.75 = 164.25
Your angles equal to 164.25 and 15.75 degrees.
Hey! Apologies that I can’t make this look nice because I’m on mobile.
To simplify this, we can multiply the denominator by its conjugate. For a imaginary function (a+bi), its conjugate would be (a-bi), so we can apply that here to multiply both sides by (2-i)/(2-i). This works because it simplifies to one. Then, we have our fraction as 4*(2-i)/((2-i)(2+i))=(8-4i)/(4-i^2)=(8-4i)/5
Feel free to ask further questions, and have a great rest of your day!
