For problem #4 the answer is 100°. The triangle are congruent meaning the angles that are given both of the triangle have to have the same angles.

The triangle sum theorem is all triangles have a 180° . All the 3 angles = 180.

They gave you two angles of the triangle. So add the two angles and find the difference of 180.

50+30=80

180-80=100°

#5 set those 2 angles equal. Because the A corresponds to Q. Solve for X and plug in your x value

Which is the best approximation of the solutions to the system of equations graphed below?
Neko [114]

According to the direct inspection, we conclude that the best approximation of the two solutions to the system of <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)

<h3>What is the solution of a nonlinear system formed by two quadratic equations?</h3>

Herein we have two parabolae, that is, polynomials of the form a · x² + b · x + c, that pass through each other twice according to the image attached to this question. We need to estimate the location of the points by visual inspection on the <em>Cartesian</em> plane.

According to the direct inspection, we conclude that the best approximation of the two solutions, that is, the point where the two parabolae intercepts each other, to the system of two <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)

NEED HELP The value of x is <br> .
Effectus [21]
The sum of all exterior angles of ANY polygon is equal to 360 degrees.

SO in this figure...
360 = 134 + 130 + x
360 = 264 + x
x = 360 - 264 = 96 degrees
