Answer:
X = 5 unit
Step-by-step explanation:
Given as , ABC is a Triangle ,
AC extended to through C to D
∠BAC = 6x + 10
∠ABC = 6x - 10
∠BCD = ∠ 8x + 20
When c extended to D then , ∠BCD is an external angle
∵ <u>External angle = Sum of opposite internal angles</u>
Or ,∠BCD = ∠BAC + ∠ABC
Or, ∠ 8x + 20 = 6x + 10 + 6x - 10
Or, ∠ 8x + 20 = 12x
Or, 12x - 8x = 20
∴ 4x = 20
So, x = 
= 5
Hence the value of X = 5 unit Answer
950 is a real number, and it is a rational number since it can be expressed as 950/1. Therefore, it falls into all of the categories expect irrational numbers.
Answer:
answer is D : 2 3/8
Step-by-step explanation:
Answer:
35
Step-by-step explanation:
All angles of a triangle add up to 180 degrees, so you can add the other two angles, then subtract by 180.
Step-by-step explanation:
9(x+1) = 25+x
open the bracket
9x + 9 = 25+x
collect like terms
9x-x = 25-9
8x = 16
x = 2
