If triangle ksd~wat, what is the measure of w? Let K=16, D=34 and T=51
valentinak56 [21]
<span>You have mentioned that two of the angles of ΔKSD are ∠K=16° and ∠D=34°. So that would mean that ∠S=130°, because∠K+∠D+∠S=180°. That's because all the angles of any triangle must total 180°. But you also say that ∠T=51°. But since no angle of ΔKSD can equal 51°, neither can any angle of ΔWAT equal to 51°. Therefore ∠T=51° is impossible!</span>

Question 13 (2 points)
Eddi Din [679]

Answer:

The math club has 22 students, and the art club has 34 students.

Step-by-step explanation:

Given that there are a total of 56 students between the art club and the math club, and that the art club has 12 more students than the math club, to determine how many students there are in each club, the following calculation must be performed:

X + X + 12 = 56

2X + 12 = 56

2X = 56 - 12

X = 44/2

X = 22

Thus, the math club has 22 students, and the art club has 34 students.

Find the inequality represented by the graph.
Korvikt [17]

Answer:

y>4x-2

Step-by-step explanation:

First let us find the equation of the line.

Given points (1,2) and (0, -2), the slope would be

(2-(-2))/(1-0) = 4/1= 4

The intercept is at -2, so the full equation would be

y=4x-2

However, we need to find the inequality of the graph. Everything greater than our line/above our line is included. Also notice that the line is dotted, which means that the line itself is not included.

Our equations should be,

y>4x-2

<em>I hope this helps! :)</em>

SSSSS [86.1K]

Answer:

  see attached

Step-by-step explanation:

I find it usually works well to draw the longest side first. Then draw arcs with radii equal to the other two side lengths. They will cross at an angle that makes the position of the third point easy to find.
