Answer:x=5 and x=-5
Step-by-step explanation:
(f-g)(x) = 4x²-2x-12 which,evaluated at x=4, gives 64-8-12=44
Answer:
∠ XWZ is a right angle.
Step-by-step explanation:
See the given diagram.
In triangle WXZ, WY is an altitude.
So, ∠ WYZ = ∠ XYW = 90°
Now, given that ∠ ZWY = ∠ WXY.
Now, from Δ XYW, since, ∠ XYW = 90° so, ∠ WXY + ∠ YWX = 90° ....... (1)
⇒ ∠ ZWY + ∠ YWX = 90° {Since, ∠ ZWY = ∠ WXY}
⇒ ∠ XWZ = 90°
Therefore, the angle XWZ is right angle. (Answer)
C=68
A= 61.
B= 119
Total degree of a triangle is 180 as well as the angle of a straight line
