To find this it would be 36/3=4/x
Then cross multiply
36*4/3
That’s the answer

We can calculate using cosinus method in triangle
c² = a² + b² - 2ab cos c
Plug in the number to the formula
c² = a² + b² - 2ab cos c
c² = 10² + 8² - 2(10)(8) cos 105°
c² = 100 + 64 - 160 cos 105°
c² = 164 - 160 (-0.26)
c² = 164 + 41.6
c² = 205.6
c = √205.6
c =14.34
C is 14.34 unit length
Answer:
975 girls
Step-by-step explanation:
To find 65% of 1500, multiply 1500 by .65 (to convert percentages to decimals, just move a decimal point over two spaces).
1500*.65=975
You can check that this answer is right with logic. Most of the students will be girls (more than 50%) and 975 makes up most of 1500.
