Answer: x = 31
Step-By-Step:
<u>To Find x:</u>
<u />
(Angle Sum Property Of Triangles)
(Remove the brackets)
<u />
<u />
(Group Accordingly)
<u />
<u />
= 
=

= 
= 
= 
= 
<u>Therefore</u> x = 31
So,
Angle A = x + 10 = 31 + 10 = 41
Angle B = 2*x + 20 = 2*31 + 20 = 82
Angle C = 2*x - 5 = 62 - 5 = 57
Answer:
55%
Step-by-step explanation:
Total number of targets = 20
Number of targets hit = 11
100 / 20 = 5
5 * 11 = 55
This means that 55% of the targets were hit.
The answer would be 15,120
The answer is 3.
the equation: 4x+6+3=17
4x+9=17
subtract 9 from both sides
4x=12
x=3
check by inserting 3 as x into the original equation
4*3+6+3=17
hope this helps!
