Answer:
m∠1 = 106
Step-by-step explanation:
Given: m∠5 = 106
Vertical angles are congruent
The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.
Therefore: m∠1 = 106
Answer:
The ordered pair that satisfies the equation is (7, -1)
Step-by-step explanation:
In order to find this, we can solve by subtracting. Start by stacking the two equations on top of one another and subtracting like terms.
3x + 3y = 18
(-) 2x + 3y = 11
--------------------
x = 7
Now that we have the value for x, we can plug in to either equation to find y.
2x + 3y = 11
2(7) + 3y = 11
14 + 3y = 11
3y = -3
y = -1
Answer:
Step-by-step explanation:
We assume the given sum is the sum of interior angles of a triangle, so is equal to 180°.
48° +X +(X -44°) = 180°
2X +4° = 180° . . . . . . . . . . collect terms
X +2° = 90° . . . . . . . . . . . .divide by 2
X = 88° . . . . . . . . . . . . . . . subtract 2°
Then the other interior angle is ...
(X -44°) = 88° -44° = 44°
The unknown interior angles are ...

Corresponding Part of Congruent Triangle
Answer:
3n+4 or n3+4
Step-by-step explanation:
7,10,13,16
they all have a difference of 3
so that's 3n
start with the first one: 3(1)+?=7
7-3=4
3n+4
use this for the other ones to double check
3(2)+4
6+4=10
