Answer:
286 degrees and 143 degrees
Step-by-step explanation:
When line intersect the two vertical angle adds up to 180 degrees
To find the other vertical angle:
180 -37=143 degrees
So for two vertical angles
we take (180*2)-(37*2)=286 degrees
Answer:

Step-by-step explanation:
Represent the SAT score with y and the rate with r.
So, we have:


Required
Determine the equation in slope intercept form
First, we calculate the slope

This gives:


Convert percentage to decimal


Multiply by 1000/1000



The equation is then calculated as:

This gives:

Open Bracket

Convert percentage to decimal



Make y the subject


Check the picture below.
bearing in mind the a solution is where both graphs intersect.
The answer to the question is 15x+30-64
First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O.
m∠O = 2 (65°) = 130°
Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°.
m∠O + m∠C + m∠B + m∠A = 360°
Substituting the known values,
130° + 90° + 90° + m∠A = 360°
The value of m∠A is equal to 50°.
<em>Answer: 50°</em>
