Answer:
Step-by-step explanation:
a=12, b=10, c=?
a²+b²=c²
Using pythagorean theorem you can find that c= 2√61
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
Answer:
Enzo is not correct because he did not multiply the length and width by the same factor.
Step-by-step explanation:
Enzo is making a scale drawing of the rectangle below.
A rectangle has a length of 8 centimeters and width of 5 centimeters.
Suppose a new rectangle will have the length of 16 cm.
Since then the scale factor is 2.
If a scale factor is two, then the width of a new rectangle must be
But Enzo says that he can draw an enlarged rectangle that is 16 centimeters by 13 centimeters. Thus, Enzo is not correct because he did not multiply the length and width by the same factor.
