equation of f(x)
point of intersection of f(x) and x axis - (-4,0)
point of intersection of f(x) and y axis - (0,4)
Equation y = x +4
g(x) = f( kx)
= kx +4
g(-2) = -2
-2k +4= -2
-2k = -2 -4
-2k = -6
k= 3
Given: Right angles are 90 degrees.
if-then: If it is a right angle, then it's 90 degrees.
Converse: If the angle is 90 degrees, then it's a right angle.
Inverse: If it is not a right angle, then it's not 90 degrees.
Contrapositive: If the angle isn't 90 degrees, then it's not a right angle.
Bi-conditional: It is a right angle if and only if it's 90 degrees.
Answer: The measure of ∠BEF=110°.
Step-by-step explanation:
Given: In cyclic quadrilateral ABCD, ∠C = 110°
Then, ∠A+∠C=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ ∠A+ 110°=180°
⇒ ∠A = 180° - 110°
⇒ ∠A = 70°
In cyclic quadrilateral ABEF,
∠A+∠E=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ 70° + ∠E=180°
⇒∠E=110°
Hence, the measure of ∠BEF=110°.
There you go. Sorry its blurry
My best answer would be D
Hope it helped! Or correct me if I'm wrong.
