Answer:
∠ ADC = 53°
Step-by-step explanation:
Note the angle between the radius and the tangent is 90°
The sum of the angles in quadrilateral AOCB = 360°, thus
∠ AOC = 360° - (90 + 90 + 74 )° = 360° - 254° = 106°
∠ AOC is twice the angle on the circumference ∠ ADC, thus
∠ ADC = 106° ÷ 2 = 53°
3x + y = 15
5x3y = 11
This is an example of a system of equations.
A system of equations is two or more equations that can be graphed, as the solution that satisfies both equations will be the point where the lines intersect on a graph.
Desmos is a graphing calculator, and thus it allows you to visualize this system.
D. 3
You can use Pythagorean Theorem to figure this out.
a^2 + b^2 = c^2
4 would your b, and 5 would be your c. You would then solve for a.
Also, 3-4-5 triangles are just something that you can always count on. If two sides of a triangle are 3 and 4, you can count on the hypotenuse being 5. On the other hand, if you know the hypotenuse is 5 and you know one of the other sides is either 3 or 4 (let’s say 3, for example) then you know the missing side has to be the other number (which would be 4 in the example i gave).
My guess would probably be A = 21
