Answer:
sine A = four-fifths
Step-by-step explanation:
You have a rectangle triangle ABC with hypotenuse AB 35, side CB 28 and side CA 21. The angle C is 90°.
In order to calculate sin A, you take into account that:
The opposite side to angle A is side CB = 28
Hypotenuse = 35
You replace the numeric values of the hypotenuse and side BC in the formula for sinA:
In order to simply the fraction, you divide both numerator and denominator by 7:
hence, the answer is
sine A = four-fifths
Answer:
The answer is 350 sqft
Step-by-step explanation:
terrace 48 sqft
back porch is = 6x6 = 36 sqft
side deck = 3x14 = 42 sqft
playroom = 16x14 = 224 sqft
Total area of the tree house: 48+36+42+224 = 350 sqft
Answer:
y = 18
Step-by-step explanation:
The angles 8y - 102 and 2y + 6 are vertical and congruent, thus
8y - 102 = 2y + 6 ( subtract 2y from both sides )
6y - 102 = 6 ( add 102 to both sides )
6y = 108 ( divide both sides by 6 )
y = 18

Answer:
D. 3, 4, 5, 6
Step-by-step explanation:
3x + 2 > 8 . . . . . . given
3x > 6 . . . . . . . . . subtract 2 from both sides
x > 2 . . . . . . . . . . divide both sides by 2
Any set of values that includes 2 or any smaller numbers is NOT a solution set. The only set with numbers greater than 2 is ...
D. 3, 4, 5, 6
Answer:
The answer to your question is 57.3 kg
Step-by-step explanation:
a)
= 
= 6.36 X stones
b) Weight = 6.36 (x)
x = 9 stones
Weight = 6.36 (9)
= 57.3 kg
