PLEASE HELP DUE IN 15 MINUTES!!
Lera25 [3.4K]

Answer:

<h2><u>Supplementary</u></h2><h2><u>x = 34</u></h2>

Explanation:

  • Supplementary angles: Angles that measure up to 180°
  • Write an equation to find x

4x + 10 + x = 180

  • Group like terms

4x + x + 10 = 180

  • Add: 4x + x = 5x

5x + 10 = 180

  • Subtract 10 from both sides

5x + 10 - 10 = 180 - 10

5x = 170

  • Divide both sides by 5

5x / 5 = 170 / 5

x = 34

In right triangle RST below, altitude SV is drawn to
Brilliant_brown [7]

Answer:

ST = 12.2

Step-by-step explanation:

See the attached diagram of the triangle.

Here, Δ RST, Δ RSV and Δ STV all are right triangles.

If we assume that, ST = x and SR = y, then

From Δ RSV and Δ STV we get,

SV² = RS² - RV² = ST² - VT²

⇒ y² - 4.2² = x² - 10.3²

⇒ x² - y² = 88.45 .......... (1)

Now, from Δ RST, we have

ST² + SR² = RT²

⇒ x² + y² = (10.3 + 4.2)² = 210.25 .............. (2)

Now, adding equations (1) and (2) we get,

2x² = 298.7

⇒ x² = 149.35

⇒ x = 12.2 (Rounded to the nearest tenth}

So, ST = 12.2 (Answer)

Why is (5+2) to the second power is not equal to 5 to the second power plus 2 to the second power is not equal
Olin [163]
Because 5 +2 is 7 and seven to the second power is 49. On the other hand 5 squared is 25 and 2 to the second power is 4 when you ad them together you get 29 you are taking to completely different numbers to the power of two and that’s why they aren’t equal
