Answer:
20 < x < 38.
Step-by-step explanation:
An obtuse angle has a value between 90 and 180.
90 < 5x - 10 < 180
5x - 10 > 90
5x > 100.
x > 20.
5x - 10< 180
5x < 190
x < 38
C/-7+3.2=2.7
Step 1) Add 7 to both sides because what you do to one side you must do to the other
C/<u>-7</u>+3.2=<u>2.7</u>
<u> +7 +7
</u> C/+3.2=9.7
Step 2) Subtract 3.2 from both side
C/<u>+3.2</u>=<u>9.7
</u> <u> -3.2 -3.2
</u> C/=6.5
Your answer is C=6.5<u>

You need to find the area of one of those bigger triangles, and one of those smaller triangles. Then multiply each area by 6 (because there are 6 sides of the big triangles, and the 6 small triangles make up the other side) and add them together. The area of a triangle is 1/2 times base times height equals area.... Equation: 1/2 (b * h) = A
Answer:
x = 2
Step-by-step explanation:
Express the ratio in fractional form
= 
( cross- multiply )
6x = 12 ( divide both sides by 6 )
x = 2
