Answer:
y=27.8
Step-by-step explanation:
- 8^2=17^2+16^2-2(16)(17)cosY
- 8^2-17^2-16^2/-2(17)(16)=cosY
- -481/-544=cosY
- 0.8842=cosY
- Y is about 27.8
Square root of a number is 2 numbers that multiply to get 4 that are the same
first find the factors
4=2 times 2
then find the doubles and write only one from each pair
√4=2
so if you had a number like 36 then
36=2 times 2 times 3 times 3
the doubles are 2 and 3 so
√36=2 times 3=6
square root of 4 can be 2 or -2

Answer:
1. Median
2. Altitude
3. Altitude
4. Neither
Step-by-step explanation:
Median- splits the side into two congruent parts
Altitude- Makes a right angle
1. Splits the side. Median
2. Makes a right angle. Altitude
3. Makes a right angle. Altitude
4. Doesn't make a right angle or split the sides. Neither
Too add mixed numbers, first convert them to improper fractions:
34/5 + 53/10
Next, find a common denominator, which in this case is 10.
Convert 34/5 so that it has a denominator of 10 by multiplying the ENTIRE fraction by 2: 68/10
68/10 + 53/10 = 121/10
You can either give your answer in the form of an improper fraction: 121/10, or a mixed number 12 1/10
