Answer:
9,750 and 0.0000084
Step-by-step explanation:
9.75 × 10^3= 9,750 (move decimal 3 places to the right because exponent is positive)
8.4 × 10^-6 = 0.0000084 (move decimal 6 places to the left because exponent is negative)
Answer:
Not similar
Step-by-step explanation:
Two polygons are similar if their corresponding side lengths are proportional to each other. In other words, the ratio of their corresponding side lengths should be the same.
Let's find the ratio of the corresponding side lengths:
3/5 = 3/5
4/12 = 1/3
5/13 = 5/13
3/5 ≠ 4/12 ≠ 5/13
The ratio of their corresponding side lengths are not equal, therefore, the two polygons are not similar to each other.
Answer:
<em>146</em>
Step-by-step explanation:
Supllementary angles add up to 180 degrees.
<em>180-34 = 146</em>
I think before it drop it was 320
Answer:
12 mm
Step-by-step explanation:
Use Pyth Theor
9^2 + b^2 = 15^2
81 + b^2 = 225
b^2 = 144
sqrt 144 = 12
b = 12
