Answer:
1.1587855e+30
Step-by-step explanation:
Step-by-step explanation:
8x +6° +118° = 180° ( linear pair)
=> 8x = 180°-124°
=> 8x = 56°
=> x = 7°
hope this helps you.
Answer:
-2.9
Step-by-step explanation:
It's in the picture.
I dont have time to do all of these right now my apolgies but Ill explain how to do it.
The 3 angles of a triangle add up to 180.
So let me show you how to do 1.
.
.
.
1. 58 degrees
92, 30, ?
If we add together the first two angles,
92+30= 122
Knowing the total addition of all three angles would ne 180, we can subtract 122 from it to get the third angle.
180-122= 58
So we now know the last angle is 58 degrees because
92+30+58=180
