Answer:
x = 80
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 30 + 70 = 180, that is
x + 100 = 180 ( subtract 100 from both sides )
x = 80
Get all your variables on same side and solve x=-2
Answer: option 1.
x f(x)
4 log (4) 4 = 1 ... because 4^1 = 4
16 log(4) 16 = 2 .... because 4^2 = 16
64 log (4) 64 = 3 .... because 4^3 = 64
Answer: ∠ABE=20°
Step-by-step explanation:
∵ AB=BC
∴ ΔABC is a isosceles triangle
∵ ∠A=30
∴ ∠C=30
∵ The interior angle sum of triangle is 180°
∵ ∠A+∠B+∠C=180
30+∠B+30=180
∠B+60=180
∠B=120 (∠ABC)
∵ ∠EBD+∠ABE+∠ABC=linear pair
∴∠EBD+∠ABE+∠ABC=180°
4x+2x+120=180
6x+120=180
6x=60
x=10
∠ABE=2x=2(10)=20°
Hope this helps!! :)
