Answer:
122
Step-by-step explanation:
10a+2+5a-2=180
15a=180
a=12
10 x 12=120
120+2=122
legs of the triangles
Each triangle 30-60-90 is:
one leg: 15 ft => short diagonal = 2 * 15ft = 30ft
other leg, x:
tan(30) = 15 / x => x = 15 ft / tan(30) = 25.98 ft
=> long diagonal = 2 * 25.98ft = 51.96 ft
side of the rhoumbus = hypotenuse of one triangle
side of the rhombus = √ [ (15)^2 + (25.98)^2 ] = √(900) = 30 ft
Area of the rhombus:
4 * area of one triangle = 4 [base*height/2] = 4*15*25.98/2 = 779.43 ft^2
The shortest distance accross the garden is equal to the side of the rhombus = 30 ft
Answer:
x = 3.4
Step-by-step explanation:
Step 1: Isolate <em>x</em>
0.5x = 1.7
Step 2: Divide both sides by 0.5
x = 3.4
And we have our final answer!
