Answer:
1.66667
Step-by-step explanation:
4 x ? = 12 ? = <u>3</u>
so,
z x ? = 5
5/<u>3</u> = 1.6666667
Answer:
the third side is 9.43
Step-by-step explanation:
the length from his head to the shadow of his head is the same as
+ =
so we solve this to get c = 9.43
<h3>Answer: x = 50</h3>
========================================
Explanation:
The angles shown are vertical angles. Any pair of vertical angles are always congruent (i.e. equal)
Set the two expressions equal to each other and solve for x.
2(x+10) = 3x-30
2x+20 = 3x-30 ... distribute
2x+20-2x = 3x-30-2x ... subtract 2x from both sides
20 = x-30
20+30 = x-30+30 ... add 30 to both sides
50 = x
x = 50
---------
Check:
Plug x = 50 into the equation. Both sides should result in the same value
2(x+10) = 3x-30
2(50+10) = 3*50-30
2(60) = 3*50-30
120 = 150-30
120 = 120
The answer is confirmed.
