Step-by-step explanation:
Answer:
43.8 (44 to the nearest degree)
Step-by-step explanation:
sin^-1(9/13) is the formula used.
The triangle has a 45-deg angle.
The base angles are congruent and measure 67.5 deg.
The congruent sides measure 1 ft.
Use law of sines to find the length of the base.
Draw a height from the vertex of the 45-deg angle to the base.
Half of the base is 0.765 ft/2 = 0.383 ft
We can find the height of the triangle using the small triangles.
0.383^2 + h^2 = 1^2
h = 0.9239 ft
A = bh/2 = 0.765 * 0.9239/2 ft^2
A = 0.354 ft^2
Answer:
Option c
Step-by-step explanation:
Because the line is moving back which is negative, and it is an open circle so it wouldnt be and equal too signs so your anwser would be c.
