Answer:
Step-by-step explanation:
x + 70 = 180 {Linear pair}
x = 180 - 70
x = 110
y + 82 = 180 {linear pair}
y = 180 -82
y = 98
x - 4 = 110 - 4 = 106
2y - 40 = 2*98 - 40
= 196 - 40
= 156
Because the left side sqrt is multiplied by 3 if it was just added it would be correct because it would cancel out and leave the 3’s. Since it’s multiplied it would change the value
67 percent is your answer
Answer:
∠CDE = 14°
Step-by-step explanation:
Since CE is extended to point F then ∠FED is an external angle of the triangle
The external angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
∠FED = ∠ECD + ∠CDE ← substitute values
4x + 5 = x + 8 + x + 9, that is
4x + 5 = 2x + 17 ( subtract 2x from both sides )
2x + 5 = 17 ( subtract 5 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Hence
∠CDE = x + 8 = 6 + 8 = 14°
