Answer:

You would need to use the Pythagorean Theorem

Step-by-step explanation:

First, you would want to take the Hypotenuse of 3 and square. Do the same for the 2.25. After that, you want to put in a calculator (Desmos Graphing Calculator) √3²-2.25² adn get the answer for the line of C and D (-2.06). After that, you do the same but on the other side: Take the Hypotenuse of 4 and the -2.06 and form it into √4² -2.06². Your final answer would be...

x = 3.43

Answer:

Both triangles are right triangles because the angle d is 90 degrees in both sides

3 ^ 2 - 2.25^2 = 1.98

4^2 - 1.98^2 = 3.48

x = 3.48

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+10)^{\circ}∠A=(7x+10) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ ,

Answer:

108 degrees

Step-by-step explanation:

Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:

Combine like terms: 14x - 16 = 180

Add 16 to both sides: 14x = 196

Divide both sides by 14: x = 14

Now that you know x, you can plug it into the expression for angle A (7x+10):

A = 7(14) + 10 = 98+10 = 108
