Answer:
66
Step-by-step explanation:
Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.
So angle 2 is 57.
Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:
57+57+angle 1=180
114+ angle 1=180
angle 1= 66

Answer:
i did the first
Step-by-step explanation:
1st way
Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5
y = -2/3*X^2-16/3*X-17/3
X = -4 ±√( 15/2) = -6.7386, or -1.2614
Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)
two real roots: X=-1.2613872124776866 and -6.738612787477313
