Cross product property

Mathematics
1 answer:
Klio2033 [76]3 years ago
8 0

Using the cross product property on this proportion gives us the following equation:

20 (2x - 9) = 10 (9)

Use the distributive property and multiply

40x - 180 = 90

Add 180 to both sides

40x = 270

Divide 40 from both sides

x = 270/40

Simplify fraction

x = 27/4

This should be your answer. Let me know if you need any clarifications, thanks!

Classify the triangle by its sides and angles
Montano1993 [528]
This is an acute scalene triangle

The triangle is acute since all three angles (58, 57, 65) are less than 90 degrees

The triangle is scalene as the angles are all different. So this leads to the sides being different lengths. No two sides are the same length.
