Given:
The measures of the angles in a triangle are in the ratio of 2:2:4.
To find:
The exterior angle that is adjacent to the largest angle.
Solution:
Let the interior angles of the triangle are 2x, 2x and 4x respectively.
According to the angle sum property, the sum of interior angles of a triangle is 180 degrees.
Clearly, x=22.5>1, so 4x is the largest angle between 2x, 2x and 4x.
Now,
Let the required exterior angle that is adjacent to the largest angle be y.
Interior angle and adjacent exterior angles are supplementary, so their sum is 180 degrees.
Therefore, the exterior angle that is adjacent to the largest angle is 90°.
(2,-1)
(x-y)
4(2) + 3(-1) = 5
4×2=8
3×-1= -3
8+(-3)=5
i hope that helps i dont know how to explain it any better
Answer:
Given that measure 2 is 79 degrees, we know it'll be <u>supplementary</u> to angle 1 meaning that that both angle measures 1 and 2 will equal 180 degrees:
79 + x = 180
-79 -79
x = 101, ∠1 = 101°
Angles 2 and 4 are <u>vertical</u>, so they are congruent meaning they measure the same degrees:
if ∠2 = 79, then ∠4 is also equal to 79°
Now that we found the measure of angle 1, we can determine the measure of angle 3 since they are <u>vertical</u> as well, (vertical angles are congruent, meaning they measure the same degrees):
if ∠1 = 101, then ∠3 is also equal to 101°
The slope is for this table is equal to 0.75
A negative change is the same thing as subtraction. So, 32.6 minus -8.25 is 40.85.
