In the diagram, AC is a diameter of the circle with center 0. If m ZACB = 50°, what is ZBAC?
1 answer:
Answer:
40degrees
Step-by-step explanation:
Find the diagram attached
Since the triangle ina semi circle is a right angle, hence <B = 90degrees
Also frm the diagram
<A + <B + <C = 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 180 - 140
<A = 40degrees
Hence the measure if m<BAC is 40degrees

X + 2y = -4
-x -x
2y = -x - 4
Divide all by 2
y = -x/2 - 2
y = (-1/2)x - 2
