Answer:
15. x = 10 3/11
16. ∠Q = 75°
Step-by-step explanation:
<h3>15.</h3>
The two base angles of the isosceles triangle are congruent, so both are 180°-8x. The sum of those, together with the apex angle, will be 180°.
... 2(180 -8x) + (5x -67) = 180
... 360 -16x +5x -67 = 180 . . . . . eliminate parentheses
... -11x = -113 . . . . . subtract 293
... x = 113/11 = 10 3/11
_____
<em>Note on the solution</em>
This value of x makes the interior base angles of the triangle be 97 9/11°. The apex angle is then -15 7/11°. The solution is correct—all the angles add up properly—but the geometry cannot exist.
_____ _____
<h3>16.</h3>
The approach is the same. The sum of the two congruent base angles and the apex angle is 180°.
... 2(2x+15) + x = 180
... 5x + 30 = 180
... x = (180 -30)/5 = 30
... (2x +15)° = (2·30 +15)° = 75° = angle Q
Answer:
0.79 ft ≈ For 30 feet
Step-by-step explanation:
This is even a tricky question for me, I am pretty sure this would be around 0.79 feet. But I am not too sure so I am very sorry if I am incorrect.
I hope this helps, if it doesn't then just message me and ill be more than happy to help :)
B. That is the correct answer because h(14) = 63 when you divide it by 3
The answer to this problem is 403.6
You only have the % and you need the number. For example i got a 87% on my Math test what is that as a decimal? The answer is 0.87 because you move the decimal ahead 2 numbers.
