From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°
Firstly, we will let this mystery number we are finding be labelled as x. Double this number can be written as 2x. 5 less than double this number is written as 2x - 5. And because this number is between -7 and 13, we have the full inequality, -7 < 2x - 5 < 13.
To solve this inequality, we want to isolate x, so we add 5 to all 3 parts of the inequality. Doing so cancels out the - 5 in the middle, so our new inequality is -2 < 2x < 18. Now we want to divide all 3 parts of the inequality by 2 to isolate x, so now our final inequality is -1 < x < 9. Thus, we can say that x is between -1 and 9.
84+92+87+104=367
500-367=133

Answer:
15
Step-by-step explanation:
Let index 1 refer to the first point, while index 2 refers to the second one.
The distance d:
d²=(x2-x1)²+(y2-y1)²=(-5-7)³+(3-(-6))²=
(-12)²+9²=144+81=225=15²
d=15
