Step-by-step explanation:
Lines AC and BC are radii of the circle, which means that triangle ABC is an isosceles triangle.
Since triangle ABC is an isosceles triangle, the measures of the base angles CBA and CAB are equal.
We know that the measure of angle CBA = 28º so the measure angle CAB must also equal 28º because the base angles of an isosceles triangle are equal.
Line ED is perpendicular to the radius AC and tangent to circle C at point A.
Therfore, angle EAC is equal to 90º and angle DAC is equal to 90º.
Angle DAC is made up of angle CAB and angle DAB.
So the measure of angle DAC (90º) minus the measure of angle CAB (28º) equals the measure of angle DAB.
90º - 28º = 62º
The measure of angle DAB is 62º
Answer:
the probability that a plain pencil is chosen from the first box is 7/12.And the probability that a color pencil is chosen from the second box is 1/2.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The amount of sides on the shape are increasing, like 4, 5, 6, so the best answer should be 7 sides for the next shape, however there is no shape that is 7, so C which has 8 sides is the next best answer.
Answer:
It's 37
Step-by-step explanation:
The given data set is ;
40,33,37,54,41,34,27,39,35
We arrange the data set in ascending order to obtain;
{27,33,34,35,37,39,40,41,54}
The median is the middle number {37}
The "number" . . . . . . . . . . . ' Q '
Three times the number . . ' 3Q '
Five less than that . . . . . . . ' <em>3Q - 5</em> '
