Answer:
Step-by-step explanation:
since you are learning about similar triangles... i'd guess that some where of the picture.. there is some words that say, that the two smaller triangles are the same, similar , congruent.. so that we can just add up angles 1 + 2 or
13 + 13 = 26 °
Answer:
20(4 + 5)
Step-by-step explanation:
GCF is just the biggest number each value can be divided by. Here, it's 20, so that goes outside of the parenthesis. Now, what can you multiply by 20 to get 80? 4, so that goes in the second box. What can you multiply by 20 to get 100? 5, so that goes in the last box. You can check your answer by doing 80 + 100 = 180; 20(9) = 180.
Example: 2x + 6 < -8
There's 2 steps to solve this one.
2x + 6 < -8
Subtract 6 from both sides
2x < -14
Divide both sides by 2
x< -7
3x + 5x = 320
8x = 320
x = 40
3(40) : 5(40) = 120 : 200
The best answer would be Option C.
1 kg = 1,000,000 mg
55,000 mg = 55,000/1,000,000 = 0.055 kg
0.055 kg < 2 kg
so 55,000 mg < 2 kg
