The missing angle would be :
90°[right angle] + 45° = 135
180 - 135 = 45°
I took 135 away from 180 because angles in a triangle always add up to 180°
Answer: 21.9ft
Step-by-step explanation: please see attachment for explanation. Thanks.!
6x-2=46;6x=48;x=8
Therefore, x is equal to 8
Since the triangle is equilateral (you can tell by the tick on each side), all angles have the same measure as well.
The angles of a triangle sum up to 180 degress, so three equal angles must measure 60 degrees each.
So, in particular, we have
7x + 4 = 60 7x = 56 x = 8
Answer:
C
Step-by-step explanation:
congruence means duplicate so you have to see its reflection
