CD = x
BC = y
AB = 85
BD = BC+CD = y+x
tan(angle) = opposite/adjacent
tan(28) = BC/AB
tan(28) = y/85
85*tan(28) = y
y = 85*tan(28)
y = 45.1953016912257
tan(angle) = opposite/adjacent
tan(31) = BD/AB
tan(31) = (y+x)/85
tan(31) = (45.1953016912257+x)/85
85*tan(31) = 45.1953016912257+x
51.0731526173427 = 45.1953016912257+x
51.0731526173427-45.1953016912257 = 45.1953016912257+x-45.1953016912257
5.877850926117 = x
x = 5.877850926117
So CD is roughly 5.877850926117 meters
Answer:
90 tens
Step-by-step explanation:
We know that there are 10 tens in a hundred, so this will be our unit rate for the rest of this problem. Since we have 9 hundreds, we have to multiply by 10 to get our answer.
9 × 10 = 90
The answer to our question is 90 tens are in 9 hundreds.
%/100 =is/of
Good equation our teacher taught us and the one you’re looking for put x
Answer:
No. (-1/2) is not an integer
Integers involve all the no. +ve and -ve. which can be written without fraction. ie whole no. are counted as integers.
(-1/2) is a fraction
If we simplify like terms on left and right sides we gwt
16x + 9 = 4x
Its B
