Answer:
Step-by-step explanation:
So we have the expression:
Distribute. Multiply (4x+5) to each term:
Distribute:
Combine like terms:
Add and simplify:
And this is in descending order, so it's in standard form.
The angle measures of any triangle = 180
adding 27 and 63. = 90
leaving 90 degrees for the remaining angle
therefore the triangle is a right triangle
by definition if a triangle has a 90 degree angle it's a right triangle
The answer is x= - 11/ 16
You can check this by plugging in x for -11/16
135
cross multiply 9*20 then divide by 8
