Answer:
A - 19.5
Step-by-step explanation:
A Rhombus is characterized by the diagonals meeting at a right angle. Therefore, the angle in the center is 90 degrees.
If you look at the bottom triangle, you know that the angles of a triangle add up to 180 degrees. You can say that all of the angles of the triangle added to 180 are:
(3x + 12) + (x) +(90) = 180 degrees
4x + 102 = 180 degrees combining like terms
4x + 102 - 102 = 180 - 102
4x = 78
4x/4 = 78/4
x = 19.5 degrees
Answer:
10.6 units
Step-by-step explanation:
distance formula
= √((x2-x1)²+(y2-y1)²)
= √((5+3)²+(-6-1)²
= √(8²+(-7)²)
= √ (64+49)
= √113
= 10.6
Answer:
<A=50
Step-by-step explanation:
85+x+55+x+50=180
2x+190=180
2x=180-190
2x=-10
x=-5
A=x+55
A=-5+55
A=50
Because it’s a square garden each side is the same meaning 84/4 will give you the length of each side, in this case 21. to work out the area it is length x width so 21 x 21 is 441!
