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
The correct answer is:
measurement of one angle and length of one side

Answer:
a=2
Step-by-step explanation:
5+14a=9a-5 subtract 9a from both sides
5+5a=-5 subtract 5 from both sides
5a=-10 divide by 5 on both sides
a=-2
hope you do well :)
