Answer:
Step-by-step explanation:
We have been given a circle. We are asked to find the measure of arc CD for our given circle.
We can see that radius of our given circle is 7 units. We can also see that length of segment CD is 7 units as well.
Since radii of circle are equal, so third side of triangle will be 7 units as well.
Our given triangle is an equilateral triangle as all sides are equal. So measure of each angle will be 60 degrees.
We know that measure of central angle is equal to its intercepted arc. We can see that arc CD intercepts to central angle of 60 degrees, therefore, measure of arc CD is 60 degrees as well.
Answer:
slope = -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = - 12 ( subtract 2x from both sides )
3y = - 2x - 12 ( divide all terms by 3 )
y = - x - 4 ← in slope- intercept form
with slope m = -

Answer:
In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10
Step-by-step explanation:
90 * x - 90 * 12 = 90(x - 12)
From the question, x = 10
Hence,
90(10 - 12)
(90* 10) - (90 * 12) - - - > correct evaluation
900 - 1080
= - 180
Hence, both values in the bracket, that is 10 and - 12 should be multiplied by 90. Not just 10 alone.
