<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>
Let the angle be 2y, 3y and 5y.
We know that sum of all angles is 180
180 = 2y + 3y + 5y
180 = 10y
180/10 = y
18 = y
2(18) = 36⁰
3(18) = 54⁰
5(18) = 90⁰
9514 1404 393
Answer:
36°, 54°, 90°
Step-by-step explanation:
We have to assume that the given measures are <em>angle</em> ratios, not <em>side</em> ratios. Sides in the ratios 2:3:5 will not form a triangle.
For some multiplier x, the angle values will total 180°.
2x +3x +5x = 180
x = 180/(2+3+5) = 18
Then the angle measures are ...
2x° = 2·18° = 36°
3x° = 3·18° = 54°
5x° = 5·18° = 90°
The angle measures are 36°, 54°, and 90°.

Use the formula of the Pythagorean theorem. a^2 + b^2 = c^2
a = 11.5
b = 18
11.5^2 + 18^2 = 456.25^2
Sqrt(456.25) to find c
c=21.36 in.

Answer:
n=4
Step-by-step explanation:
Distribute the 8. and then subtract 8n from both sides and divide 40 and 10n.
A=1/2×b×h
18=1/2×b×6
18=3×b
b=6
