Answer:
Step-by-step explanation:
solution:
given:- BE is bisector of ∠DBC and BE//AC
statement reasons
1. ∠DBE= ∠BEC 1. since, BE is bisector of ∠DBC
2.∠DBE=∠BAC 2. corresponding angle are equal
are equal.
3.∠EBC=∠BCA 3. alternative angle are equal
4.∠BAC=∠BCA 4. from statement 1,2,3
5 therefore, triangle ABC is 5. if base angle are equal it is a an isosceles triangle isosceles triangle
6. AB=BC 6.corresponding sides of equal angle
isosceles triangle are equal
proved
Angle 2 and Angle B are both the same
180-50-65= 65 (angle sum of a triangle is 180 degrees) B = 65 degrees
180-50-65= 65 (angle sum on a straight line is 180 degrees) 2= 65 degrees
Thus Angle 2 and Angle B are both the same
f(x)= -0.5(x-5)^2+8
The 2 exponent following the parentheses indicates it is a quadratic equation, which means it will have a parabola shape. The negative sign in front of the -0.5 indicates the parabola will open down. The + 8 indicates a translation of 8 spaces upward.
