Answer:
6 1/4, 6 3/7, 6.5, 6.625
Step-by-step explanation:
6 1/4 is 6.25 so that makes it the smallest and 6 3/7 is still small and everything else is easy
Complementary angles have the sum of 90 degrees
Add angle A and angle B
(8x+27) + (6x-21) = 90
14x + 6 = 90
14x = 84, x = 6
Plug 6 into angle B equation
6(6) - 21 = 36 - 21 = 15
Solution:
Open the compass it is more than half of the distance between a and b, and scribes arcs of the same radius centered at a and b. call the two points where these two arcs meet c and d. Draw the line between c and d. CD it is the perpendicular bisector of the line segment AB. call the point where CD intersects AB and E
Answer:
Step-by-step explanation:
First note that the triangles shown are isosceles triangles due to equality of two of their sides which is radius. So their baseline angles are equal
Since their middle angle are equal too, so their 3 angles are the same. It menas both triangles are similar.
However, we know two of three sides are equal, but the third should be also because of their similarity.
y+4 = 2y - 3
2y - y = 4 - 3
y = 4+3
y = 7
Therefore,
2y-3 = 2.7-3 = 14-3 = 11
Answer is 11 centimeters
