Answer:
D. Yes, two sides are perpendicular, and the side lengths fit the
Pythagorean theorem.
Answer:
x = 80
Step-by-step explanation:
x + 30 = 110 (opposite sides are congruent/equal)
x = 110 - 30 (subtract the 30 from both sides to get X by itself)
x = 80 (simplify)
Common difference = 2nd term - first term
= -13-(-6)
= -13+6
= -7
The distributive property of multiplication is a very useful property that lets you rewrite expressions in which you are multiplying a number by a sum or difference.
Answer:
Step-by-step explanation:
If we let the measure of the smallest angle be 
, then we know that the measure of the angle that is three times as large as it is 
and the measure of the angle that is 
larger than it is 
.
Because the sum of the measures of the interior angles in a triangle is 
, we can write the following equation to solve for :
Solving for , we get:
(Combine like terms)
(Subtract 
from both sides of the equation to isolate , Simplify)
Therefore, the measures of the other angles are 
and 
. Since 
, the measure of the largest angle will be 
. Hope this helps!
