Find the answer to X
Karo-lina-s [1.5K]

Answer:

23

Step-by-step explanation:

100 is the exterior angle.

( 2x + 3 ) and 51 are interior angles.

Formula : -

Exterior angles = Sum of two interior angles.

100 = 2x + 3 + 51

100 = 2x + 54

2x = 100 - 54

2x = 46

x = 46 / 2

x = 23

Find y.<br> Round to the nearest tenth:<br> 290<br> 500 ft<br> y<br> X<br> y = [ ? ]ft
hjlf

Answer:

  • y = 242.4
  • x = 437.3

First find the inner angle:

  • 90° - 29°
  • 61°

[ given hypotenuse = 500 ft ]

using sine rule:

\sf sin(x)= \dfrac{opposite}{hypotensue}

\hookrightarrow \sf sin(61)= \dfrac{x}{500}

\hookrightarrow \sf x=sin(61)*500

\hookrightarrow \sf x=437.3

using pythagoras theorem:

  • a² + b² = c²
  • y² + (437.3)² = 500²
  • y = √58760.1
  • y = 242.4
