Answer:
Step-by-step explanation:
From the given triangles in the picture attached,
∠A ≅ ∠X [Given]
∠B ≅ ∠Y [Given]
By AA property of similarity of the triangles, both the triangles will be similar.
ΔABC ~ ΔXZY
Similarity statement:
Corresponding sides of these similar triangles will be proportional.
Similarity ratio:
=
= 3 : 2
Answer:
The perimeter is cm.
Step-by-step explanation:
Perimeter is found by adding all sides of the triangle together. So, this is what we need to find:
Look at the number under the radical: 7, 63, and 28. These numbers all share a factor of 7: 7/7 = 1, 63/7 = 9, 28/7 = 4.
Notice how 9 and 4 are perfect squares, so we can simplify the radicals using this common factor of 7.
remains the same;
; and
. Now they are like radicals and can be added!
Answer:
0.00007935
Step-by-step explanation:
7.935 x 10 to negative 5 power can be written as:
7.935 x 10^(-5)
A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000
When dividing by tens, move the decimal to the left by the amount of 0's
So our answer is 0.00007935
