1.) I belive the first one is 40 because a triangle is 180 degrees so that means that if you add 85 and 40 it would equal 125 so 180-125= 55 so F is 55 now again L is 85 so 85+55=140 so 180 -140=40 so H is 40
First step- convert the mixed numbers into improper fractions
second step- make sure the improper fractions have the same denominator
last step, add/subtract the two fractions and simplify if possible
Answer:
11/25
Step-by-step explanation:
44% can be written as a Fraction as 44/100. This fraction can ultimately be simplified to 22/50 before being finally reduced again to 11/25.
Answer:
15/2 sqrt(3) =z
15/4 sqrt(3) =y
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse in a right triangle
cos 30 = z / 15
Multiply each side by 15
15 cos 30 = z
15 ( sqrt(3)/2)
15/2 sqrt(3) =z
sin theta = opposite side/ hypotenuse in a right triangle
sin 30 = y / z
Multiply each side by z
z sin 30 = y
z (1/2)=y
Z = 15/2 sqrt(3)
15/2 sqrt(3)*1/2
15/4 sqrt(3) =y
