PLEASE HELP< GEOMTREY SUCKS!!!!!!!!!
Andrews [41]

Answer:

The measure of angle DCB = 125

Step-by-step explanation:

This is because angle ACD and angle DCB are supplementary.

Supplementary angles are two angles with a sum of 180 degrees, and we know these angles are supplementary by the fact that angle ACB = 180 degrees.

1. Given GH = 7x + 3, HI= 3x - 5,<br> and GI= 9x + 5.<br> H<br> G<br> A. Find x:<br> B. Find GH:
blsea [12.9K]

Answer:

\boxed{\bf x=7}

\boxed{\bf GH= 52}

Step-by-step explanation:

In the line segment..

\bf 7x+3+3x-5=9x+5

Combine like terms.

  • \bf 10x-2=9x+5

Add -2 to both sides.

  • \bf 10x-2+2=9x+5+2
  • \bf 10x=9x+7

Subtract 9x from both sides.

  • \bf 10x-9x=9x+7-9x
  • \boxed{\bf x=7}

\bf GH=7x+3

  • \bf 7(7)+3
  • \bf 49+3
  • \boxed{\bf 52}

ExtremeBDS [4]
Given the function h(x)=\arcsin(x)

Part a:

Considering the input of h

i.) A valid unit of measure for the input quantity is Seconds

ii.) The possible input values, i.e. the domain of h are -1 ≤ x ≤ 1



Part B:

i.) A valid unit of measure for the output quantity is the Radians.

ii.) The possible output values, i.e. the range of h is 0 ≤ h ≤ 2π



Part C:

i.) \arcsin\left(\sin\frac{\pi}{3}\right)=\frac{\pi}{3}

ii.) \arcsin\left(\sin\frac{2\pi}{3}\right)=\frac{2\pi}{3}

iii.) \arcsin\left(\sin\frac{7\pi}{6}\right)=\frac{7\pi}{6}

iv.) \arcsin\left(\sin\frac{7\pi}{4}\right)=\frac{7\pi}{4}
