Answer:
<h3>x =11</h3>
Step-by-step explanation:
Using the triangular law which states that the sum of interior anggle of a triangle is equal to exterior angle
From the diagram
Interior angles = 5x +10 and 58
Interior angle = 11x+2
Equate both expressions
5x + 10 + 58 = 11x+2
5x - 11x = 2 - 10 - 58
-6x = 2-68
-6x = -66
x = -66/-6
x = 11
<em>Hence the value of x is 11</em>
Right triangle
Sin A = Opp./ Hypo. = BC/AC
Cos C = Adj./Hypo. = BC/AC
Answer is D.
Sin A = Cos C
2x+3x+4 is equivalent with 5x+4 and 3(4x+2) is equivalent to 12x+6 and then the last two
Only the dividend is stated. there's no divisor
