Answer:
c 108
Explanation:
r/6=18
Multiply both sides by 6 to cancel it out on the left side
6r/6=18*6
r=18*6
r=108
I hope this helps!
Answer:
- 2
Step-by-step explanation:
5x + 3x = - 10 - 6
8x = -16
x = -2
<h3>
Answer: 133</h3>
=============================================================
Explanation:
The quickest way to get this answer is to add the angles given to get 87+46 = 133
This is through the use of the remote interior angle theorem.
Note how the angles 87 and 46 are interior, or inside the triangle. And also, they are not adjacent to the exterior angle we want to find. So that's where the "remote" portion comes in.
----------------
The slightly longer method involves letting x be the measure of the missing interior angle of the triangle.
The three interior angles add to 180
87+46+x = 180
133+x = 180
x = 180 - 133
x = 47
The missing interior angle of the triangle is 47 degrees.
Angle 1 is adjacent and supplementary to this 47 degree angle, so,
(angle1)+(47) = 180
angle1 = 180-47
angle1 = 133 degrees
This example helps confirm that the remote interior angle theorem is correct.
Answer:
180
Step-by-step explanation:
x+10, 2x+15, and 3x-13. what are the degree measures of the angles of the triangle? The sum of the measures of the angles of triangle = 180 degrees.
