Help me with 24 “ find the value of x”
2 answers:
Vertical angles are always congruent. Therefore you must set them equal to each other. If we set 2x+20=3x+15 we can do the math like so
2x+20=3x+15
-15 | -15
2x+5 | 3x
-2x | -2x
5 | X
Now to check the answer 2*5+20=30
3*5+20=30
30=30
X=5 is the correct answer. Hope this helped and happy geometry!
Answer:
x = 5°
Step-by-step explanation:
2x+20 = 3x +15 —> Opposite angles
3x - 2x = 20 - 15
x = 5

Step-by-step explanation:
conditions : x≠0 and x≠-a and b≠1
1/(x+a) = b/x ⇌ 1×x = b(x+a) ⇌ x = bx + ba ⇌ (1-b)x = ab ⇌ x = ab/(1-b)
x = 3/2 or -1/3
The number before the decimal and the first number after the decimal and the last number
-3 times -3=9
9-(-3)=9+3
9+3=12
