Answer:
No, these triangles are not similar.
Step-by-step explanation:
Similar triangles have the same angle measures.
Knowing that the angles in a triangle add up to 180 degrees, find the missing angle, and you will see that the angles in the triangle are not congruent to each other, meaning that the triangles are not similar.
Step-by-step explanation:
1.828 x 10 ^3 is standard for 1828
8000-2600=5400
5400/12=450
monthly pavement =450
12x450+2600=8000
Answer:
50°
Step-by-step explanation:
As usual, the diagram is not drawn to scale.
The chord divides the circle into two arcs that have a sum of 360°. If we let "a" represent the measure of the smaller arc, then we have ...
a + (a+160°) = 360°
2a = 200° . . . . . . . . . . . subtract 160°
a = 100°
The measure of the angle at A is 1/2 the measure of the subtended arc:
acute ∠A = a/2 = (1/2)·100° = 50°

<em>Comment on this geometry</em>
Consider a different inscribed angle, one with vertex V on the circle and subtending the same short arc subtended by chord AB. Then you know that the angle at V is half the measure of arc AB. This is still true as point V approaches (and becomes) point A on the circle. When V becomes A, segment VA becomes tangent line <em>l</em>, and you have the geometry shown here.
