I need help with this problem answers is right there but show me how to get that answer

Olin [163]

First you find P which would be 16+17+17 which equals 50. Then you find B which is 1/2•16•15 which equals 120. Next you write the formula which would look like 50(20)+2(120) which equals 1240!

Find the missing lengths in the triangle. round to the nearest tenth if necessary

lubasha [3.4K]

Answer:

$x=8,\\y\approx 6.9$

Step-by-step explanation:

The side lengths of all 30-60-90 triangles are in ratio $x:x\sqrt{3}:2x}$ , where $2x$ is the hypotenuse of the triangle and $x$ is the side opposite to the 30 degree angle.

In the given diagram, the side labelled 4 is opposite to the 30 degree angle. Since $x$ is labelled as the hypotenuse of the triangle, $x$ must be $4\cdot 2=\boxed{8}$ .

Variable $y$ must then represent $x\sqrt{3}$ for $x=4$ , yielding $y=4\sqrt{3}\approx \boxed{6.9}$

What is 1/3 add 1/4

Harrizon [31]

$\frac{1}{3} + \frac{1}{4} = \frac{1\times 4}{3\times 4} + \frac{1\times 3}{4\times 3} = \frac{4}{12} + \frac{3}{12} = \frac{4+3}{12} = \boxed{\frac{7}{12}}$
