Use what you know about the angle sum theorem for triangles and your algebra skills to solve for x and find the measure of all t
melomori [17]

Answer:

2x° = 45°, 3x° = 67.5°

Step-by-step explanation:

Sum of angles in a triangle = 180°

2x+3x+3x=180°

8x=180°

x=22.5°

2x=22.5°x2=45°

3x=22.5°x3=67.5°

True [87]

Answer:

∠ 1 = 20°, ∠ 2 = 160°

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and are supplementary, that is sum to 180°

x - 12 + 5x = 180 , that is

6x - 12 = 180 ( add 12 to both sides )

6x = 192 ( divide both sides by 6 )

x = 32

Thus

∠ 1 = x - 12 = 32 - 12 = 20°

∠ 2 = 5x = 5 × 32 = 160°

How do I do this problem? <br> (Similar triangles)
MA_775_DIABLO [31]

Answer:

x = -78

Step-by-step explanation:

Write and solve an equaiton of ratios, as follows:

hypotenuse to hypotenuse:

         57                 51

 ----------------- = ---------------

      2x + 7             x + 4

Cross-multiplying, we get:

57x + 228 = 102x + 351

Combining the x terms on the right, we get:

          228 = 45x + 351

Combining the constants on the left:

           -123 = 45x, and so x = -123/45 = -78

x = -78
