Seven eighth, 7 over 8, 7/8, 0.875,
Answer:
∠ 1 = 20°, ∠ 2 = 160°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and are supplementary, that is sum to 180°
x - 12 + 5x = 180 , that is
6x - 12 = 180 ( add 12 to both sides )
6x = 192 ( divide both sides by 6 )
x = 32
Thus
∠ 1 = x - 12 = 32 - 12 = 20°
∠ 2 = 5x = 5 × 32 = 160°
Assume L=1.5W, where W=width, L= Length of the triangle.
Therefore,
Perimeter (P) = 2(W+L) = 2(W+1.5W) = 2(2.5W) = 5W=20 => W=20/5 = 4 in
Then, L=1.5W = 1.5*4 = 6 in
Area, A= L*W = 6*4 = 24 in^2
