Answer:
A. 48
Step-by-step explanation:
There is a diameter of the circle through point O. The bottom right angle is an inscribed and that intersects a diameter, so its measure is 90 deg.
a + 90 + 42 = 180
a + 132 = 180
a = 48
Group the xs and the ys, 17+5= 22x 3+1=4y so y=4 and x=22.
Y=-x+8
gradient of the parallel line is the same as the gradient of the line given, which is -1
to find the y-intercept, sub the values (9,-1) into the equation we are finding which is y=-x+c
Answer:
The number -5 is a real number is true.
