One leg of a right triangle measures 6 inches. The remaining leg measures 6 StartRoot 3 EndRoot inches. What is the measure of t
Usimov [2.4K]

Answer:

∅ = 30°

Step-by-step explanation:

given data

side 1 = 6 inches

side 2 = 6\sqrt{3}  inches

to find out

angle opposite the leg that is 6 inches long

solution

we  will use pythagoras theorem that is express as

hypotenuse² = perpendicular²   + base²     .......................1

put here value and we get  hypotenuse

hypotenuse² = 6² + (  )²

solve it we get

hypotenuse²  = 144

hypotenuse = 12 inches  

now we apply here sin∅ that is

sin∅ = \frac{perpendicular}{hypotenuse}     ................2

put here value and we get

put here value and we get

sin∅ = \frac{6}{12}  

∅ = sin^{-1}(0.5)  

solve it we get

∅ = 30°

HELP PLEASE I NEED HELPPPP
nlexa [21]

Answer:

174 inches squared

Step-by-step explanation:

First, we have to remember what the area of a triangle is:

\frac{base*height}{2}

Since there are 4 of the same triangle, multiply the area of one triangle by 4:

\frac{10*8.7}{2}

\frac{87}{2}

43.5

43.5(4)=174

Please help!! What is RS?
Reil [10]

Answer:

<h2>         RS = 47</h2>

Step-by-step explanation:

RV=VU and SW=WT    means    VW=\frac{RS+UT}{2}

So:

3x+5=\dfrac{2x+15+6x-37}{2} \\^{\qquad\times2\qquad\qquad\qquad\qquad\times2} \\6x+10=8x-22\\^{\qquad-10\qquad-10}\\6x=8x-32\\^{-8x\qquad-8x}\\-2x=-32\\^{\div(-2)\quad\div(-2)}\\x=16\\\\RS=2x+15=2\times16+15=32+15=47
