4 0

Answer:

x = 58°

Step-by-step explanation:

51 = 1/2(160 - x)

102 = 160 - x

102 - 160 = -x

-58 = -x

   x = 58°

What is the solution set to the equation (2x – 6)(3x – 4) = 0?
yan [13]
Well if you are asking for the 2 values of x, then you would get this by setting each parenthesis to 0 this will result in 2x-6=0 now add the 6 to both sides and get 2x=6 now divide by 2 to get 3 your first x is 3 now lets do the next one, 3x-4=0 add the 4 to both sides and get 3x=4 now divide to get x=4/3 sp your 2 sets would be x=3 and x=4/3

Hope this helped

If ΔOPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about segment R prime S prime?
Sergio [31]

Answer:

\overline {R'S'}  = 3 {\overline {RS} }

Step-by-step explanation:

The scale factor of dilation of triangle ΔOPQ, S.F. = 3

The center of dilation = Point <em>Q</em>

Therefore;

The length of the segment, {\overline {S'Q'} } = 3 × The length of the segment, {\overline {SQ} }

Similarly;

The length of the segment, {\overline {R'Q'} } = 3 × The length of the segment, {\overline {RQ} }

By Pythagoras theorem, we have;

{\overline {R'Q'} }^2 = {\overline {R'S'} }^2 + {\overline {S'Q'} }^2

Therefore;

{\overline {R'S'} }^2  = {\overline {R'Q'} }^2  - {\overline {S'Q'} }^2 = \left ({3 \times \overline {RQ} } \right) ^2  - \left (3 \times {\overline {SQ} } \right) ^2 = 9 \times \left (\overline {RQ} }  ^2  -  {\overline {SQ} } ^2 \right) = 9 \times  {\overline {RS} }^2

\therefore \sqrt{  {\overline {R'S'} }^2} =  \sqrt{ 9 \times  {\overline {RS} }^2}= 3 \times  {\overline {RS} }

\overline {R'S'}  = 3 \times  {\overline {RS} }.
