Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
C doesn’t have a value , x equals 0 , x=0
Answer:
All I know
Step-by-step explanation:All I know is that you have to distribute the top so 5{2k - 3} so that would be 10k-15 and then -3{k+4} would be -3k -12 hopefully this helps you out a littble bit so the top completely is 7k-27
Answer:
θ=1.2 rad=68.7549°
Step-by-step explanation:
Given
- Circle of radius 5
- Arc of length 6 subtends angle of θ

⇒

θ
Therefore θ=1.2 rad
(π rad= 180°)
Therefore 1.2 rad= 68.7549°
50/80 = 0.625
100 - 0.625 = 0.375
0.375 = 37.5% (move the decimal point to the right 2 spaces)
37.5% decrease is your answer
hope this helps
