Answer:
1st: 5x
2nd: 6ft
Step-by-step explanation:
I really don't know how just got the answer right.
Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.

<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
You know that Akiko is 45 miles from the origin...Kosuke is (135/4) miles from the origin... You can draw a figure to clearly see the situation.
<span>you "know" that the angle between their routes is 140º </span>
<span>the side opposite (140º) is the distance between them... </span>
<span>c^2 = (45)^2 + (135/4)^2 - 2(45)(135/4) cos 140 </span>
<span>c ≈ 74.1 mile
Hope this answers the question.</span>
Answer:
(16π - 32) in²
Step-by-step explanation:
In the picture attached, the circle is shown.
Area of one-quarter of circle = 1/4*Area of a circle = 1/4*π*radius² = 1/4*π*8² = 16π in²
Area of the triangle = 1/2*base*height = 1/2*8*8 = 32 in²
Shaded area = Area of one-quarter of circle - Area of the triangle = (16π - 32) in²
