Cos(40)= 21/ (hypotenuse)
hypotenuse(cos(40))= 21
hypotenuse = 21/ cos(40)
21/ cos40 = 27.41
Answer:
Step-by-step explanation:
ASSUMING the given dimensions are the lengths of the legs
we have an equilateral triangle with base 4 and height
h = √(3² - (4/2)²) = √5
A = ½bh = ½(4)(√5) = 2√5 cm²
Answer:
21 hours
Step-by-step explanation:
We can use a ratio to solve
7 houses 30 houses
------------- = --------------
5 hours x hours
Using cross products
7x = 5*30
7x = 150
Divide by 7
7x/7 =150/7
x =21.42857143
Rounding to the nearest whole number
x = 21 hours
Answer:
Step-by-step explanation:
since it is 100% and the pie chart circle is 360°, then for each % it will be 3.6°
applying this into drawing, just times 3.6° to the percentage and then get the final angle for the data.

Answer: 50.24=A
Step-by-step explanation:
I know because i used the equation the radius which is half of the diameter=8 half of 8 is 4 and 4 squared is 16 so 16+3.14 which is pie = 50.24
