Answer:
<h2><em><u>y = -30</u></em></h2>
Explanation:
-240 = 8y
8y = -240
8y / 8 = -240 / 8
<h2><em><u>y = -30</u></em></h2>
- PNW
31°
Angles in the same segment are similar.
I'm not too sure how to explain, but in a circle when two "triangles" are formed from two same points on the circumference, the angle of the vertexes formed are the same (like in the picture)
The answer is: [A]:
_________________________________________________
input: number of rowers number of rowers in the rowboat;
output: speed of the rowboat ;
_________________________________________________
NOTE: The input would be the independent variable and plotted on the "x-axis" of the graph; and the output would be the dependent variable and plotted on the "y-axis" of the graph.

Answer:
the height is 18cm
Explanation:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Are these ratios equal?
given that
Triangle 1 (first triangle)
base = 10cm
height = 15cm
Triangle 2 (second triangle)
base = 12cm
height = unknown
base 1 / base 2 = height 1 / height 2
10cm / 12cm = 15cm / xcm
xcm = 18cm
height = 18cm
Answer:
AAS Postulate.
Step-by-step explanation:
The AAS Postulate states that if 2 angles and a non-included side are congruent on both triangles, then the two triangles are equivalent.
In this case, the first Angle is: ∠B ≅ ∠D (Given, both are 90° in measurement)
For the side: Line BE ≅ line DE (Given)
∡BEA ≅ ∡DEC (Definition of Vertical Angles)
AAS Postulate is therefore used.
