Answer:
82
Step-by-step explanation:
Sides AB and BC are equal, which means angle BAC and BCA have the same measure, as stated in the base angles theorem. Angle BAC is 49 degrees, so angle BCA must also be 49 degrees. The sum of all angles in a triangle is 180 degrees, so angles BAC, BCA, and CBA will add up to 180. Write this in an equation:
BAC+BCA+CBA=180
BAC and BCA both measure 49 degrees:
49+49+CBA=180
Solve for CBA
CBA=180-49-49
CBA=82

Set up a proportional fraction relating RSV and RTU. Before doing that, sort out what RT is equal to;
Now, we can equate SR/SV with RT/TU. This is something we can do because they are similar, and therefore should have equal ratios between sides.
Cross multiply them, and solve for x.
That being said, the little cutout at the top left claims the answer is 8. If you verify my answer, it works out.

Answer:
Step-by-step explanation:
Steve and Elizabeth invest money in a 3:4 ratio, respectively. This means that Steve invests $3x and Elizabeth invests $4x.
They need $80,000 for the franchise, then
3x+4x=80,000,
7x=80,000
Thus, Elizabeth invests
