Answer:
x=90°
y=55°
Step-by-step explanation:
A
D
C
B
let the triangle be named ABD
angleABD= 1/2 angleACD[ being angle formed at same
] arc
=1/2×180
= 90
now,
angleX + angleY + 35° = 180 [ sum of the angle
of the triangle]
90 + Y + 35 = 180
Y= 180-125
Y = 55
2x is not a way to express this. You could use 2 + x or x +2. But 2x is x multiplied by 2. x + 2 is x plus 2.
Answer:
x=0, x= - 3, x=9
Step-by-step explanation:
f(x)=7/2x(x+3)(x-9)
f(x) doesn't exist for x=0,-3,9
as

vertical asymptote:
x=0, x= - 3, x=9
Answer:
33
Step-by-step explanation:
since the whole thing is a right angle=90 you just subtract it from 57 and that's 33
